1. Option C is correct
Sexual reproduction is a result of gamete fusion. Gametes are produced via meiosis and during meiosis DNA undergoes recombination leading to the production of new variants. Random fusion of gametes and DNA from the two different origin also contributes to the creation of new combinations and diverse phenotype. Variations helps in the process of evolution.

Which of the following statements is FALSE? a. In sexual reproduction, offspring receive two genes for every trait. b. Asexual reproduction produces clones. c.

Increased genetic diversity for changing environments B. The elimination of genetic mutations from a parent organism C. The receipt of the strongest genes from both parents for survival D. The creation of new genes to improve survival
11) Ciliates generally have a micronculeus and a macronucleus. During conjugation the micronuclei are exchangea between two compatible mates (haploid) resulting in diploid micronuclei. How is this similar to bacterial conjugation? A) physical touching occurs B) it is sexual, allowing recombination of genes C) it is not a form of reproduction, no new cells arise D) all of the above are shared characteristics of bacterial and ciliate conjugation 12) Protista is the most diverse of all the kingdoms containing single...
