Sexual reproduction leads to offspring that are all genetically different from one another and from either parent. What are the three aspects of sexual reproduction that lead to this variation?
a) shuffling and reassortment of homologues during mitosis; shuffling and reassortment of homologues during meiosis; and combination of alleles from two parents at fertilization.
b) crossing over during the production of zygotes; shuffling and reassortment of homologues during mitosis; and combination of alleles from two parents at fertilization.
c) crossing over during the production of gametes; shuffling and reassortment of homologues during mitosis; and combination of alleles from two parents during binary fission.
d) crossing over during the production of gametes; shuffling and reassortment of homologues during mitosis; and combination of alleles from two parents at fertilization.
e) crossing over during the production of gametes; shuffling and reassortment of homologues during meiosis; and combination of alleles from two parents at fertilization.
Ans: e) crossing over during the production of gametes; shuffling and reassortment of homologues during meiosis; and combination of alleles from two parents at fertilization.
