When A Diploid Cell Undergoes Normal Meiotic Division, Then All :

A: Dominant Genes Segregate Together
B: Homologous Chromosomes Segregate
C: Daughter Cells Will Have Different Homologous Chromosome Pairs
D: Linkage Groups Will Be Disrupted

The answer is: B

Explanation

The correct answer is B: Homologous Chromosomes Segregate. During meiosis, homologous chromosomes segregate from each other and are distributed to different daughter cells. This process results in the formation of haploid daughter cells, each containing one set of chromosomes. The segregation of homologous chromosomes is important for generating genetic diversity among offspring.

Option A is incorrect because dominant genes do not necessarily segregate together during meiosis.

Option C is correct but not complete as it is a consequence of the segregation of homologous chromosomes.

Option D
is incorrect because linkage groups may or may not be disrupted depending on whether the genes are located on the same chromosome or not.
