The process by which homologous chromosomes exchange genetic materialMultiple Choiceis crossing over.is random fertilization.occurs only in bacteria.occurs only in animals.is independent assortment.

What is crossing over?Group of answer choicesalso referred to as the “independent assortment of chromosomes”the exchange of homologous portions of nonsister chromatidsmaking an RNA copy of a DNA stranda direct consequence of the separation of sister chromatidsthe movement of genetic material from one chromosome to a nonhomologous chromosomethe exchange of homologous portions of sister chromatidsNext

Which of the following processes occurs when homologous chromosomes cross over?Group of answer choicesMaternal alleles are “corrected” to be like paternal alleles and vice versa.Corresponding segments of sister chromatids are exchanged.Two sister chromatids get tangled, resulting in one re-sequencing its DNA.Corresponding segments of nonsister chromatids are exchanged.Two sister chromatids exchange identical pieces of DNA.Next

Genes that are on different chromosomes will migrate independently of genes on other chromosomes during gamete formation.Group of answer choiceslaw of segregationmultiplication rulelaw of independent assortmentaddition ruleNext

During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material

Crossing over, random orientation of chromosomes, and random fertilization are mechanisms involved in meiosis and sexual reproduction that generate diversity.
