Question

The locations for three genes have been added to this cartoon. For clarity, the locations have only been noted on one chromatid. The lowest frequency of crossovers would occur between genes ____ and ____.

Answer 1

This cartoon now includes the locations of three genes. The positions have only been noted on one chromatid for simplicity's sake. Genes a and b would cross across with the least frequency (closest together on chromosome)

One of a chromosome's two identical halves that has undergone replication in order to facilitate cell division is referred to as a chromatid. The centromere, a constrictive area of the chromosome, serves as the connection between the two "sister" chromatids.

During meiosis and mitosis, chromatin fibers are used to make chromatids. When DNA is wrapped sequentially around skeletal proteins, the structure is known as a nucleosome and is referred to as chromatin. Chromatin fibers are even more densely wrapped nucleosomes. DNA can be compressed by chromatin to fit into the nucleus of a cell. Chromosomes are made of threads of condensed chromatin.
