A pure-bred red cow crossed with a pure-bred white bull, produces all roan offspring (has a mix of both red hairs and white hairs). Roan-colored cows and bulls display a. Codominance b. Incomplete dominance c. Pleiotropy d. Complementary genes e. Epistasis

Explanation / Answer

29. e. Mitotic anaphase

Given that, the chromosomal number in the given cell is 2n = 4 or n = 2. The chromosomal number in the mitotic anaphase is 4n (in this case, 4n=8). During anaphase, centromeres are pulled and the chromatids become separated and move towards the opposite poles. These chromatids now are the chromosomes of the daughter cells, and are pulled towards the centrioles by means of spindle fibres.
