Answer is Meiosis.
Meiosis is the process by which most eukaryotic organisms form sex cells or gametes. During prophase of meiosis I, the homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement. The exchange of chromosome segment between non-sisters chromatids forms new combination of genes on a chromosome can lead to new traits in offspring. The process helps increase the genetic diversity of a species.

Answer:
Explanation:
<u>a. How many chromosomes does a child receive from its father?</u>
Every person receives half of their chromosomes from their father and half from their mother. For that reason, if humans have 46 chromosomes in each somatic cell, 23 of them come from the father.
<u> b. How many autosomes and how many sex chromosomes are present in each somatic cell? </u>
Each somatic cell has 46 chromosomes in total; of which 22 pairs are autosomes and 1 pair are sex chromosomes. Therefore, 44 chromosomes are autosomes and 2 chromosomes are sex chromosomes (the X and/or Y chromosomes).
<u>c. How many chromosomes are present in a human ovum? </u>
The human gametes (ovum in women and sperm cell in men) have half of a somatic cell's genetic material, so that when they combine in a zygote to create their child, they form an initial cell with 46 chromosomes in total. The ovum therefore has 23 chromosomes: 22 autosomes and 1 sex chromosome.
<u>d. How many sex chromosomes are present in a human ovum?</u>
As I mentioned in the previous question, a human ovum has 1 sex chromosome. That way, when it combines with a sperm cell, which also has 1 sex chromosome, they form a zygote with <u>a pair</u> of sex chromosomes (one that comes from the mother and one from the father).
Ribosomes is responsible for the production of proteins in the cell.
<h3>What is ribosomes?</h3>
A ribosome is a cellular organelle which is made of RNA and protein that serves as the site for protein synthesis in the cell. Ribosomes are present in cells that prepares large amounts of protein so we can conclude that Ribosomes is responsible for the production of proteins in the cell.
