Answer:
100%
Explanation:
Assuming the gene for polydactyly is represented by P. Normal finger will be represented by p.
A woman that is homozygous for polydactyly trait will have genotype PP while a man with normal 5 fingers and toes will have the genotype pp (since P is dominant over p).
PP x pp = Pp, Pp, Pp and Pp.
All the offspring will have the genotype Pp and since P is dominant over p, it means all the offspring will have polydactyly trait.
<em>Hence, the percentage of the offspring of the couple that would be expected to be polydactyly is 100%</em>
"Adjacent chromatids in homologous chromosomes cross over during meiosis in sperm and egg formation" is the one among the following choices that describes what <span>causes genetic variation during human sexual reproductive processes. The correct option among all the options given in the question is the second option.</span>
Answer:
The correct answer will be option-C.
Explanation:
The RNA polymerase is the enzyme which synthesizes the mRNA molecules using a single strand of DNA. RNA polymerase has the ability to bind nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.
In the given question, gene expression of the insulin-producing gene has been discussed which uses transcription factors. The transcription factors assist RNA polymerase enzyme to attach to the promoter sequence and start synthesizing RNA molecule.
Thus, Option-C is the correct answer.
