Question

A major advantage of sexual reproduction over asexual reproduction is genetic variation of offspring the cost of cell division the number of offspring that can be generated A & B A, B, .& C Which of the following can be considered mechanisms of genetic recomination? Fertilization Crossing over Independent assortment A & B A, B, and C Two plants are crossed resulting in offspring with a 3:1 ratio for a particular trait. Assuming Mendelian genetics, what does this suggest? the traits show incomplete dominance each offspring has the same alleles for the two traits blending of traits occurs the parents were true-breeding the parents were heterozygous

Explanation / Answer

16. A

Explanation: formation of gametes and fusion of gametes take a long time over asexual reproduction, and less no of offspring will be generated as fertilization barrier and the long duration for the formation of tissue system as well as organs.

17. E

Explanation

Fertilization is fusion of male and female gametes, which causes genetic changes

Crossing over is a process of the homologous chromosome where they exchange their genes.

independent assortment: During fusion of gametes any gamete having any sequence of a species which leads to recombination.

18. E

the parents were heterozygous
