Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. a true-breeding female (aabb) with 6-cm ears is mated to a true-breeding male (aabb) with 16-cm ears. predict the ear length of the f1 generation. (note: assume that each allele contributes equally to ear length, and the genes segregate independently. also assume that environmental influence on ear length is negligible.)

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.

Answer

The location of a gene found here is at the short arm of chromosome 17 at the specific point of the short arm of 23.6 on the chromosome.

Meaning of the address 12p7.2

12- chromosome 12

p- short arm of chromosome 12

7.2- exact point of the short arm on chromosome 12. The position of the gene on the p or q arm. The position of a gene is based on a distinctive pattern of light and dark bands that appear when the chromosome is stained in a certain way.

These addresses allow scientist and doctors to have a quick and easy way to reference specific genes to where they are which gives insight into their location.
