A triallelic gene determines a person's blood type according to the allele combination. This gene expresses complete dominance and codominance. Option B) Jethro is right and is a winner-winner (chicken dinner).
What is the ABO blood type?
The ABO blood type is determined by a triallelic gene I. Depending on the allelic interaction, this gene can express complete dominance or co-dominance. Let us see,
Alleles
IAIBi→ IA and IB are codominant, meaning that when they are together in the same genotype, both of them are expressed.
→ IA and IB express complete dominance over i, meaning that the dominant IA and IB alelles hide the expression of the recessive allele i in heterozygous individuals.
Genotypes Phenotype
IAIA, IAi ⇒ Blood type A
IBIB, IBi ⇒ Blood type B
IAIB ⇒ Blood type AB
ii ⇒ Blood type 0
Now, let us analyze the situation,
Ellie May has B blood type. Her genotype might be either homozygous IBIB or heterozygous IBi.Ellie May had a child who has 0 blood type (genotype ii). This child inherited two recessive alleles, one from each parent. This fact suggests that Ellie May is heterozygous (IBi), and she provided an i recessive allele to the child. The other recessive allele must have been inherited from the father.Jethro has A blood type and he is homozygous IAIA, which means he could not provide the other recessive allele to the child. He can not be the father. The biological father can be either IAi, IBi, or ii.
The correct option is b) Jethro is right and is a winner-winner (chicken dinner).

following an action potential, a nerve cell goes through a brief refractory period during which it cannot be stimulated. what is true during this refractory period?
following an action potential, a nerve cell goes through a brief refractory period during which it cannot be stimulated. It facilitates the unidirectional flow of the action potential.
Action potential are the electric signal generated by the neurons which occurs to transfer the signal around the body. It occurs by temporary shift in the neuron's membrane potential which is caused due to sudden inflow of the ions.
It is divided into depolarization, repolarization, hyperpolarizatio and refractory period.
In refractory period the nerve cell enters a resting phase and are not able to transfer any action potential.

look at the progeny from the cross of ttyy x ttyy. how many phenotypic classes were expected in the resulting progeny?
In the progeny, 63 phenotypic classes were expected.
Only 1/16 of the progeny will likely have short green seeds 1008/16 is 63.
Which phenotypic classes are there?Then, phenotypes can be used to distinguish between various genotype-related hypotheses, where phenotypes are a class of creatures that only share a subset of their total set of features and genotypes are a class of organisms that share a subset of their germ cells.
Why is phenotype significant?It is possible to increase agricultural production to meet the demands of the expanding human population by establishing the relationship between genotype and phenotype. Therefore, in order to prove the causal link between genes and phenotypes, phenotyping is just as crucial as genotyping.

A community that is fully developed and rich in biodiversity. Within this society, there are extensive and intricate food webs. A thick layer of dirt and hardwood trees are present is Climax community
A climax community is the final ecological successional stage that a plant community may attain. Animal and plant succession occur at the same rate. When pioneer species have demonstrated that life is feasible in the region, more advanced plants and animals will move in and establish themselves as well. Climax communities arise because the local environment has allowed for ecological equilibrium to be attained, according to their presence. Climate conditions determine the kind of plant communities that may persist, leading to the complicated ecological relationships and vast variety of niches that are the distinguishing characteristics of a climax community. a natural environment where plant and animal populations are steady and get along well with one another and their surroundings. A climax community is the final stage of succession, and it exists until it is destroyed by a natural disaster or human activity. additional info at succession.
Examples include tropical, deciduous, and coniferous rain forests as well as deserts, tundra, grasslands, and grasslands. To ensure stability, a process known as succession is undertaken, in which relatively basic communities are replaced by more complex ones.
Therefore, grass may encroach into a sand deposit along a beach. In the humus that the grass has produced, oaks, pines, and other smaller plants establish themselves, displacing the grass and generating fresh, modified humus. Such soil subsequently produces maple and beech trees, which eventually displace the pine and oak trees to form a climax community. A range of new living forms can also be found in each subsequent community, with the climax community having the most variety.

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.
The size of the fetal face is one-third the size of the fetal cranium while the adult skull is two-thirds the size of the adult cranium.
The face of a fetus is foreshortened and overshadowed by its cranium. Also, his mandible and maxilla are very tiny. On the contrary, the adult cranium is comparatively smaller and his facial bones are comparatively larger than the cranium.
Cranium is the outer protective layer of the skull. It comprises 8 cranial bones and 14 facial bones. It has two main parts: cranial roof and cranial base. The cranial roof consists of frontal, occipital and two parietal bones. The cranial bases also comprises these three types of bones and also includes sphenoid, ethmoid and temporal bones.
The cranial bones are connected by connective tissues during infancy to allow their growth and form one piece. The primary function of cranium includes protecting the brain and providing a link for the attachment of facial muscles.
The size of the fetus ' face increases as it matures and thus has a very small face compared to its cranium. The cranium in the adult is all grown up and does not grow further.

Name the two main organ systems that communicate within the body to maintain homeostasis.
The two important body systems that interact inside the body to ensure homeostasis are the endocrine system and central nervous system .
The principal control systems for ensuring homeostasis are the central nervous and endocrine systems. The endocrine system is made up of glands that generate chemical regulators (hormones). The nervous system senses discrepancies from the brain's normal equilibrium (homeostasis) and sends information to the internal organ in order to compensate. It restores the required balance in a fairly short amount of time. Both systems function mostly instantaneously, however the nervous system could be voluntarily controlled.

those may also be used at the side of other commonplace modifiers that describe the unfold and severity of the lesion.
Apoptotic, oncotic, or blended types of "person mobile necrosis" (every now and then known as "single cellular necrosis") might also arise. Oncotic necrosis is regularly described the use of greater conventional terminology like "coagulation necrosis," which has a similar that means.

The phenetic, or phenotypic classification, is a primary approach used in biology to divide organisms into categories. The phenetic technique combines species following their observable phenetic characteristics; two species will be classified together if they resemble one another more than either does any other species. Species can be classified according to the cellular arrangement, gram stain behavior, and flagella.
The complete categorization makes up a taxonomic hierarchy of levels where individuals from higher and higher levels of a group appear to be less and less similar to one another. The classification of species phenetically does not require any knowledge of evolution, in contrast to the phylogenetic principle.
