In an F2 population of cross, if 50% recombinant individuals are observed. Which one of the following is the main cause for this?

Answer: Option A

In an F₂ population of the cross, 50% recombinant individuals are observed. Segregation is the main cause of this.
The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells.
The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete.
