Question

use only one chromosomal pair in each blank box you fill in. you may not need to use all the chromosomal pairs. there may be more than one correct answer. which chromosome pair(s) would work in box a? bb bb bb g g gg

Explanation:

Step1: Analyze the key for alleles

The key shows that the alleles for the trait in question are represented by pairs. Box A is a non - sex chromosome pair (autosome pair). Alleles for autosomes are in pairs. Options \(G\) and \(g\) are single alleles (not pairs), so they are incorrect.

Step2: Check the format of allele pairs

The pairs \(BB\), \(Bb\), \(bb\), and \(Gg\) are all pairs of alleles. Since box A is for a chromosomal pair (which carries allele pairs), these are valid as they represent pairs of genes (alleles) on a chromosome pair.

Answer:

BB, Bb, bb, Gg
