In his experiments,Mendel noted that when two traits are involved in a genetic cross,they are inherited independently of each other.The reason for this is that
A)genes on the same chromosome separate during the formation of gametes.
B)alleles on the same gene separate during the formation of gametes.
C)genes on different chromosomes separate during the formation of gametes.
D)alleles on the same chromosome separate during the formation of gametes.
E)chromosomes often recombine.

Question

Quizplus · Accepted Answer

Genes on different chromosomes separate and assort independently during the formation of gametes, leading to independent inheritance of traits. This is known as the law of independent assortment. Genes on the same chromosome may sometimes be linked and inherited together, but this is not always the case. Alleles on the same gene do not separate during the formation of gametes, as they exist at the same locus on the chromosome. Therefore, options A, B, and D are incorrect. Chromosomes recombine during meiosis, which can sometimes lead to the separation of linked genes, but this is not the main reason for independent assortment, so option E is also incorrect.
