quiz 5

What are the primary processes that increase genetic variability?

• sexual reproduction and mutations

• cloning and binary fission

• asexual reproduction and mitosis

• budding and recombination

The variety of possible gene combinations in a sexually reproducing species is due in part to the

• sorting of genes as a result of gene replication.

• sorting of genes as a result of meiosis.

• pairing of genes as a result of mitosis.

• pairing of genes as a result of differentiation.

The sorting and recombining of genes during meiosis and fertilization usually leads to the production of

• embryos with traits identical to those of all other members of the species.

• gametes with additional copies of the same chromosome.

• offspring with some traits that did not appear in their parents.

• zygotes with the genetic information to produce only females.

Which mechanism is present in meiosis that allows for variety of characteristics in offspring

• mutations and elimination of genes

• sorting and recombination of genes

• crossing over and asexual reproduction

• overproduction and selective breeding

When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs

• crossing over
• mutagenesis
• hybridization
• fertilization
