Butler, Ricki Lewis 1,402 solutions What are results of genetic crosses?The results of genetic crosses can be predicted using a chart called a Punnett square. In a Punnett square, the possible male and female gametes of each parent are written across the side and top of the square. The interior squares represent every possible combination of gametes that could combine to form a zygote.
What is the relationship between the degree of crossing over and the distance between two genes?It follows that: • the probability of a crossover between two genes is proportional to the distance between the two genes. That is, the greater the distance between the two genes, the greater the probability that a crossover will occur between them during meiosis.
Why does more crossing over occur between two distantly linked genes than between two genes that are very close together on the same chromosome?The basic reason is that crossovers between two genes that are close together are not very common. Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.
What does a recombination frequency of 50% indicate?Answer and Explanation: A frequency of recombination of 50% indicates that the genes are independently assorting. For genes found on separate homologous chromosome pairs, we would expect all of the various allele combinations to be equally probable.
