D , over a period of time. I know becuase i have studied science forever almost. But Yes, over a period of time is correct.
What is you talking about boaaa
Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm
Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC
Number of dominant alleles if length is
18 cm = 18-6 / 4 = 12 / 4 = 3.
F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.
seven 1. It is likely that there are gene pairs in this cross. There are
categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.

<span>This would allow the insulin to be created much faster than if it was required to be made naturally. By having a ready supply on-hand at all times, those who desperately needed it would not have to worry about being hospitalized every time their blood sugar level dropped too low.</span>
