Question

How do variations occur in offsprings? Explain.(5marks question) so plz answer accordingly.

Answer 1

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism'soffspring).

Answer 2

Meiosis is the process by which gamete cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization. The genetic recombination of genes also occurs during crossing over or the swapping of gene segments in homologous chromosomes during meiosis
