Remarkably, all the white-eyed flies were male. What was the explanation for this result? A) The gene involved is on an autosome. B) The gene involved is on the Y chromosome. C) Other male-specific factors influence eye color in flies. D) The gene involved is on the X chromosome. E) Other female-specific factors influence eye color in flies. 30) 25) How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE? A) 8 B) 32 C) 64 D) 4 E) 16

Explanation / Answer

22- The correct answer is option D That is IV.

Mitosis is represented by the number IV.

23- The correct answer is option B that is II.

As in dna synthesis amount of dna increases, so it is represented by II.

23 - The correct answer is option D that is the gene involved is on the X chromosome.

24 - There are three heterozygotes in the genotype that is Aa, Bb and Dd. So, 23=8

So, correct answer is option A that is 8.
