Mendel’s law of segregation has its physical basis in which of the phases of the cell cycle?

Meiosis

Explanation:

Because that's when alleles of different genes cross over, specifically in Prophase I.

it has physical basis in Meiosis I particularly Anaphase I and meiosis II particularly Anaphase II.

Explanation: Because in Anaphase I spindle get far apart from each other and chromosomes segregation results. In this phase as a result of segregation 2 daughter cells are formed and in Anaphase II, 4 haploid cells are formed.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

option a and d is the correct answer

i hope this u

plz mark as the brainliest answer
