Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell. They contain all the genetic information of an organism. Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?
A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.
D)The cell cycle stops, allowing for extra haploid cells to be made.

Answer:

C

Explanation:

I am pretty sure answer is C.

Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

The chromosomes present in the parent cell duplicate in the S phase of the cell cycle, and in the meiosis phase of the cell cycle, the daughter chromatids segregate and form four haploid cells from the parent cell. The child or offspring is the result of the fertilization of the sperm and the ovum, and the zygote is formed from the process that develops into the offspring, and the zygote has half the genetic contents of the paternal and maternal parents. In this way the chromosomes separate in the meiosis.

Hence, Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.
