Geographical variation refers to differences among populations in genetically based traits across the natural geographic range of a species. ... In the simplest case, we divide these factors into purely genetic versus environmental components to tease apart their relative contributions to observed phenotypic variation.
Answer:
The ear length will be 11 cm.
Explanation:
To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.
As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.
6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.
The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
