Homework Answers
There are two parents, AaBb and aabb.
Gametes formed by AaBb will be - AB, Ab, aB, ab
Gametes formed by aabb will be - ab
So, the answer which is shown in the image given in the question is correct.
Both the parents are having genes for two traits, so, this is a dihybrid cross.
Please rate high.

3) The diploid cells of A. roksiki have a total of 4 chromosomes (2n=4). One of the homologous pairs is large with an acrocentric centromere and the other is small with a metacentric centromere. A. Draw the chromosomes from A. roksiki as they would appear in metaphase 2 of meiosis. Include all cells and all chromosomes. Assume meiosis is proceeding normally and ignore any effects of crossing over. (6 pts) B. A strain of A. roksiki is heterozygous for a...

3. (4 pts). A diploid somatic cell of a hypothetical eukaryote contains two pairs of homologs in its nucleus (2N = 4). One pair of homologs is metacentric and the other pair is submetacentric. The metacentric pair is heterozygous at two gene loci and each locus is on a different arm. At one locus, the alleles are identified by the letters “A” and “a”. At the other locus, the alleles are identified by the letters “B” and “b”. The upper...
