Question

Progeny produced by ab/ab genotype when they are in different chromosomes

Answer 1

Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart. In other words, the nearer two genes are on a chromosome, the lower the chance of recombination between them, and the more likely they are to be inherited together. Markers on different chromosomes are perfectly unlinked.

Answer:

When genes are close together on the same chromosome, they are said to be linked. ... Four different phenotypic (appearance-based) classes of offspring are produced in this cross, each ...
