Where do homologous chromosomes exchange genetic material through crossing over? a. centromeres b. centrosomes c. chiasma d. chlorophyll

C. Chiasma

Explanation:

Homologous chromosomes are a pair of chromosomes which are identical with respect to the location of the genes, the centromere, and length.

An individual inherits a pair of homologous chromosomes (one form each parent) and these chromosomes pair up during meiosis to exchange genetic material.

The site where this exchange occurs is called the chiasma, which is the point where the two chromosomes come in contact with each other and exchange the material. This is known as crossing over.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
