Answer:
The correct answer is - 0.91.
Explanation:
Given that C is dominant over c with an allelic frequency of 0.7. The sum of the frequency of dominant alleles and the frequency of heterozygous alleles in this H-W population of angiosperm will be the expected frequency of red-flowered plants.
The frequency of C = 0.7
(p² = dominant allele frequency)
Then, the frequency of dominant genotype CC would be = 0.7×0.7 (p² = dominant allele frequency)
As we know that P + q = 1
then q = 1 - p
q (frequency of recessive allele) - 1 - 0.7
q = 0.3
Then frequency of heterozygous genotype Cc= 2pq
= 2×0.7×0.3
= 0.42
The frequency of red flowers = freq of CC + freq of Cc
= 0.49 + 0.42
= 0.91
Given that C is dominant over c with the frequency of 0.7
The sum of the frequency of dominant allele and heterozygous alleles in this H-W population of angiosperms expected frequency of red-flowered plants.
frequency of C = 0.7
[tex]p^{2} =dominant allele[/tex]
CC= 0.7 × 0.7
[tex]p+q =1\\q= 1- p\\= -1-0.7\\=0.3\\[/tex]
Then frequency of genoype = Cc= 2pq
= 2×0.7×0.3
= 0.42
[tex]frequency of red flower = freq of CC + freq of Cc[/tex]
= 0.49 + 0.42
= 0.91.
What is Hardy-Weinberg equilibrium?It is a principle that states genetic variation in a population will remain constant from one generation to the next generation in the absence of disturbing factors.
Hence concluded that the frequency of red-flowered plants = 0.91

Emily has a maternal grandfather who is colorblind, which is an X-linked
recessive trait. Everyone else in her family sees normally. Emily's mom is
expecting a new baby girl. What is the chance that the new baby will also
be colorblind?
A. There is no chance that the new baby girl could be color blind.
B. There is no way to determine this from the information provided.
C. There is a 25% chance that the new baby girl will be colorblind.
D. There is a 50% chance that the new baby girl will be colorblind.
Answer:
A
Explanation:
the father doesn't have the trait and since it's recessive, there's no way the baby could have it even if the mother carries it from the grandfather.
There is a 25% chance that the new baby girl will be colorblind. Therefore, the correct option is C.
What is colorblindness?Color blindness is an X-linked recessive trait. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is expressed only when there are two copies of the gene, one on each X chromosome, in females. Males have only one X chromosome, so they will express the trait if they inherit the colorblind gene.
In Emily's family, her maternal grandfather is colorblind. This means that Emily's mother is a carrier of the colorblind gene, since she does not have the trait herself. Emily's father must have two normal copies of the gene, since he does not have color blindness.
When Emily's mother and father have a child, there are four possible combinations of their genes that the child could inherit:
Normal X from mother, Normal X from father (25% chance)
Normal X from mother, Colorblind X from father (25% chance)
Colorblind X from mother, Normal X from father (25% chance)
Colorblind X from mother, Colorblind X from father (25% chance)
Only the last combination would result in a colorblind female, since she would have two copies of the colorblind gene. Therefore, the chance that the new baby girl will be colorblind is 25%.

Why is breaking and rearranging bonds in the process of photosynthesis and cellular respiration important? WILL GIVE BRAINLIEST
Answer:
Breaking and rearranging bonds in the process of photosynthesis and cellular respiration is important because energy is released when bonds are broken in both processes. This energy is used to fuel cellular activities. Bonds are rearranged in the process of photosynthesis to make molecules of glucose; this glucose is used to fuel the process of cellular respiration, in which bonds are rearranged to form molecules of water and carbon dioxide.
In photosynthesis and cellular respiration breaking and rearranging, bonds release energy.
How is the energy released in respiration?ATP, NADH, and FADH are used to store the energy that is produced when carbon bonds are broken and rearranged in living things. Every time you exhale, carbon dioxide is expelled because cells cannot utilize it.
The extremely valuable ATP molecules are readily available to fuel cellular activity. Sugars are broken down by animal and plant cells to produce useful energy.
By severing chemical bonds and building new ones while rearranging atoms, these and other chemical processes transform materials into other compounds.
Therefore bonds release energy so breaking and rearranging bonds in the process of photosynthesis.

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.
