Question

What is the source of genes in an offspring that is produced as a result of sexual reproduction?

• A. The offspring gets a full set of genes from the mother and from the father
• B. The offspring gets half the genes from the mother and half the genes from the father
• C. The offspring gets a random mixture of genes from the mother and father
• D. The offspring gets all of its genes from the mother

Answer 1

The correct option is B The offspring gets half the genes from the mother and half the genes from the father

The offspring gets half the genes from the mother and half the genes from the father. Meiosis is the process by which one diploid eukaryotic cell divides to generate four haploid cells often called gametes. Meiosis is essential for sexual reproduction and therefore occurs in all eukaryotes (including single-celled organisms) that reproduce sexually.

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

So, the correct answer is option B.
