Question

Offsprings formed during sexual reproduction exhibits more variation than those formed by asexual method, because,

• A. Genetic material comes from two different individuals
• B. Greater amount of DNA is involved
• C. Sexual reproduction is more complicated
• D. Genetic material comes from male parent

Answer 1

The correct option is A Genetic material comes from two different individuals

Sexual reproduction is a mode of reproduction where two specialized reproductive cells called gametes fuse together i.e., male and female gametes. Each gamete contains half the number of chromosomes of normal cells. So, the offspring produced contains half of the genes from the mother while half from the father. In this process, crossing over takes place where there is exchange of genetic material between homologous chromosomes that results in recombinant chromosomes which cause variations in the offsprings. Thus, the correct answer is option A.
