The normal sequence of genes along a hypothetical chromosome is ABC*DEFGH, where letters represent genes and the asterisk (*) re
Hunter-Best [27]

Answer:

The correct option is e

Explanation:

An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.

From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.

NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.

A fruit fly of genotype B R/b r is testcrossed with b r/b r. In 84 percent of the meioses, there are no chiasmata between the li
Citrus2011 [14]

Answer:

4 percent (4%)

Explanation:

A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).
