Question

Which of the following statements is incorrect?

• A. At the time of gamete formation, homologous chromosomes bearing the factors pair segregate in anaphase II of meiosis II producing two daughter cells.
• B. Both chromosomes and alleles follow law of segregation.
• C. Both chromosomes as well as genes occur in pairs in the somatic or diploid cells.
• D. In criss-cross inheritance male passes its gene on chromosome to the daughter while the son gets genes on X-chromosome from the female.

Answer 1

Answer: (A)

At the time of gamete formation, homologous chromosomes bearing the factors (genes) pair segregate (separate) in anaphase- $1$ of meiosis $1$ producing two daughter cells. In anaphase II of meiosis II, the two chromatids of each chromosome separate and enter the two new daughter cells. These four daughter cells, thus formed have one chromosome along with one allele of a gene or factor present in it.
