None of the parents

B

Single parent

C

Both parents

D

synthesis of own genes

Correct Answer :

Both parents

Solution :

The correct option is Both parents.

Detailed Explanation:

1. Origins of Chromosomes:
In sexually reproducing organisms, an individual receives one set of chromosomes from the maternal parent (mother) and another homologous set from the paternal parent (father).

2. Homologous Recombination (Crossing Over):
During Prophase I of meiosis (the cell division process that produces gametes like sperm and egg cells), homologous maternal and paternal chromosomes pair up closely. During this pairing, non-sister chromatids undergo a process called crossing over, where they physically exchange segments of DNA.

3. Creation of Recombinant Chromosomes:
As a result of this exchange, the chromatids are reshuffled. The resulting daughter chromosomes that are distributed to the gametes are recombinant, meaning they contain a mosaic of genetic material. Therefore, a single daughter chromosome carries genes originating from both parents.

4. Enhancing Genetic Diversity:
This mixing of maternal and paternal alleles ensures that every gamete has a unique combination of genes, which drives genetic variation and diversity in subsequent generations.
