one form of hereditary deafness is inherited with an x-linked recessive allele. a woman with normal hearing has a son with hereditary deafness. the woman's genotype at this gene locus is . multiple choice question. hemizygous homozygous heterozygous
The woman's genotype at this gene locus is heterozygous.
In this scenario, the woman has normal hearing which means that she has at least one dominant allele for the gene that controls hearing. However, since her son has hereditary deafness, it means that he inherited two recessive alleles for this gene (one from his mother and one from his father).
Since the gene for hereditary deafness is x-linked recessive, it is located on the X chromosome. Women have two X chromosomes while men have one X and one Y chromosome. Therefore, if a woman is heterozygous for the x-linked recessive allele, she has one dominant and one recessive allele on one of her X chromosomes, but the other X chromosome has the dominant allele.
Since the woman has normal hearing, it means that the dominant allele on her other X chromosome is sufficient to provide normal hearing. However, since she has one recessive allele for the x-linked recessive allele, she can pass it on to her offspring. In this case, her son inherited the recessive allele from his mother's X chromosome and a recessive allele from his father's X chromosome, resulting in hereditary deafness.

in a reflex arc, ___________ neurons pass out of the central nervous system to stimulate effectors.
In a reflex arc, motor neurons pass out of the central nervous system to stimulate effectors.
A reflex arc is a neural pathway that enables rapid and automatic responses to certain stimuli, ensuring quick and efficient reactions to protect the body from harm. This process consists of five main components: the receptor, sensory neuron, integration center, motor neuron, and effector.
Receptors detect the stimulus and generate an impulse that travels along the sensory neuron. This impulse then reaches the integration center, typically the spinal cord, where interneurons transmit the signal to the appropriate motor neuron. Motor neurons are responsible for carrying the signal away from the central nervous system and towards the effector, which is typically a muscle or gland. Effectors then respond accordingly, such as contracting a muscle to pull the hand away from a hot surface or releasing hormones to initiate a specific bodily response.
In summary, a reflex arc is a crucial mechanism in the nervous system that allows for quick and automatic responses to stimuli. Motor neurons play a vital role in this process, as they carry signals from the central nervous system to the effectors, initiating the necessary response.

you are studying an incredibly large eukaryotic protein. the gene that codes for this protein is approximately 304,814 base pairs long. the resulting polypeptide is 34,350 amino acids long. based on the size of the gene, how long would you expect the polypeptide to be?
Based on the size of the gene that codes for this incredibly large eukaryotic protein being approximately 304,814 base pairs long, we can expect that the resulting polypeptide would be quite long as well.
This is because the sequence of nucleotides in the gene determines the sequence of amino acids in the polypeptide, with each set of three nucleotides coding for one amino acid. Therefore, the length of the polypeptide can be estimated by dividing the number of base pairs in the gene by three.
In this case, we would expect the resulting polypeptide to be approximately 101,604 amino acids long (304,814 / 3 = 101,604). However, we are told that the actual length of the polypeptide is only 34,350 amino acids long. This suggests that there are regions of the gene that do not code for amino acids and instead serve regulatory functions, such as controlling when and where the gene is expressed. Additionally, some amino acids may be repeated or not included at all due to alternative splicing, where different combinations of exons (coding regions of the gene) are spliced together to form the final mRNA transcript.
In conclusion, while the size of the gene can give us an estimate of the length of the resulting polypeptide, there are many factors that can influence the final sequence and length of the protein.

how many genetically different gametes could be formed by a person with the genotype aa bb cc dd ee ff?
A person with the given genotype aa bb cc dd ee ff can form only 1 genetically different gamete.
A person with the genotype aa bb cc dd ee ff can form genetically different gametes.
The given genotype consists of six pairs of homozygous recessive alleles: aa, bb, cc, dd, ee, and ff. Each pair has two identical alleles, so there is only one possible combination for each pair.
To find the number of genetically different gametes, we can multiply the possible combinations for each pair:
1 (from aa) × 1 (from bb) × 1 (from cc) × 1 (from dd) × 1 (from ee) × 1 (from ff) = 1
So, a person with the given genotype can form only 1 genetically different gamete.
