Answer #1

Answer:
Option - 50%

The unit of measuring distance between two genes on a chromosome according to the frequency of recombination between them due to cross over is called a map unit (or centiMorgan /cM)

A genetic map unit of 1 mu (or 1 cM) corresponds to a recombination frequency of 1%.
In large chromosomes, the cumulative distance may exceed 50 mu but the maximum recombination frequency is 50%.
Hence Chiasma between A & B will be observed in 50% of meiotic cells.

Genes A and B have been physically mapped to chromosomal landmarks that can be seen under a light microscope. Linkage mapping involving multiple genes has resulted in a genetic map distance of 65 m.u. between A and B. A researcher observes meiotic prophases under a microscope and wants to determine which proportion of meiotic cells will show a chiasma (the physical structure formed during crossing over) between A and B. Given the genetic map distance the expectation is that a...

There are three genes - A, B, C - on the same chromosome. You have been studying gene A and know that the distance between A and B is 5 m.u. (map units), and the distance between A and C is 3 m.u. Based on the information you have, above, what are potential arrangements of all three genes on the chromosome? You can choose more than one. Note: answers give the genes and map units between them, in order. For...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...

In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection.
