Question

I'm having trouble with this question. I'm really lost please help.

2 A trihybrid has the genotype AaBbCc. Genes A and B are on different chromosomes and gene C is on the same chromosome as gene B. The diagram depicts the chromosome composition of different cells from the animal. Which of the cells could represent a mature gamete? bllb Cl B Bllb cell 1 cell 2 cell 3 cell 4 cell 5 a. cell 1 b. cell 2 c. cell 3 d. cell 4 e cell 5 3 Certain kinds of cells (e.g some cells in the eyes and bones) mature and differentiate into a state in which

Explanation / Answer

Gametes are haploid in nature and contain one copy of DNA from the body in which it is produced. Since we are asked about gametes, Cells1/3 are not possible representations. (they are represented by both copies of genes/chromosomes)

Again, it is given that gene A is in one chromosome while Genes B and C are in another chromosome. So, Cells 2/5 are also not possible. ( Cell 2 has genes A and C in one chromosome and b in another. Cell 5 has all three gene copies in both chromosomes)

Cell 4 here appropriately represents a gamete with gene A in one chromosome and gene A and C in the other. so, the answer is Cell 4.
