Question

Which of the following statements concerning chromosomal distribution is INCORRECT?

A. All human somatic cells contain 23 chromosomal pairs for a total diploid number of 46 chromosomes.
B. Each gamete contains 23 chromosomes, one member of each chromosomal pair.
C. During meiotic division, the members of the chromosome pairs regroup themselves into the original combinations derived from the individual's mothers and father for separation into haploid gametes.
D. Sex determination depends on the combination of sex chromosomes, an XY combination being a genetic male, XX being a genetic female.
E. The sex chromosome content of the fertilizing sperm determines the sex of the offspring.

Answer 1

C. During meiotic division, the members of the chromosome pairs regroup themselves into the original combinations derived from the individual's mothers and father for separation into haploid gametes.

Step-by-step explanation:

During meiosis, there is a random segregation of chromosomes. Metaphase-I of meiosis-I includes alignment of homologous pairs of chromosomes at the cell's equator.

During anaphase I, the homologous chromosomes are separated from each other and move towards the opposite poles. This segregation of homologous chromosomes to the opposite poles is a random event and creates unique combinations of maternal and paternal chromosomes at each pole and finally in each gamete.
