Question

1. ccc patterns explain why sexual reproduction results in offspring with more genetic variation than asexual reproduction.

Explanation:

Sexual reproduction involves the combination of genetic material from two parents. During meiosis, crossing - over occurs, which exchanges genetic segments between homologous chromosomes. Also, independent assortment of chromosomes during meiosis leads to different combinations of chromosomes in gametes. When gametes from two parents fuse (fertilization), the offspring get a unique combination of genes from both parents. In asexual reproduction, offspring are produced from a single parent, usually by mitosis (in eukaryotes) or binary fission (in prokaryotes). There is no combination of genetic material from two different sources, no crossing - over or independent assortment in the context of combining genetic material from two parents. So, sexual reproduction has more mechanisms to create genetic variation.

Answer:

Sexual reproduction results in more genetic variation than asexual reproduction because it involves the combination of genetic material from two parents. In sexual reproduction, meiosis has processes like crossing - over (exchange of genetic segments between homologous chromosomes) and independent assortment (random distribution of chromosomes into gametes). When gametes from two parents fuse during fertilization, the offspring inherit a unique mix of genes. Asexual reproduction, on the other hand, typically involves a single parent (e.g., by mitosis or binary fission) with no combination of genetic material from two different sources, thus limiting genetic variation.
