Explain how a genetic map (in map units) is related to actual physical distance (in base pairs of dna).

Explanation:

A map unit [or centimorgan (cM)] is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. Its relation with actual physical distances is inconsistent because the number of base pairs to which it corresponds varies widely across the genome, it also depends on whether the meiosis in which the crossing-over takes place is a part of male or female genes (female genome is 4782 cM long, while the male genome is only 2809 cM long).

I hope you find this information useful. Good luck!

Explanation:

An amoeba reproduces via the process known as binary fission.

After replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells.



OR

•Yeast is a unicellular organism. Yeast reproduces via the asexual process known as budding.

•Budding usually occurs when food is available in plenty.

•In budding, one or more outgrowths appear on one side, which increases in size.

•The nucleus divides through mitosis, one daughter nucleus passes into the bud and the other remains in the parent cell.

•The bud either separates off from the parent cell or new bud appears before its separation from the parent cell resulting in the formation of branched or unbranched chain of buds.
