What is gene linkage?

Gene linkage refers to genes that are located close to each other on the same chromosome and tend to be inherited together.

What is independent assortment in genetics?

Independent assortment is the principle that genes located on different chromosomes assort independently during meiosis.

What are linked genes?

Linked genes are genes that are located on the same chromosome and often do not assort independently.

What is meiotic recombination?

Meiotic recombination is the process during meiosis where linked genes may become separated, leading to new combinations of alleles.

How does the frequency of recombination relate to genetic mapping?

The frequency of recombination can be used to determine the arrangement and distance of genes on a chromosome in a genetic map.

What types of genetic conditions are associated with the X chromosome?

Conditions like hemophilia A and B, Hunter syndrome, and colorblindness are associated with mutations on the X chromosome.

Why is independent assortment possible according to Mendel's experiments?

Independent assortment is possible for traits studied by Mendel because those traits were located on different chromosomes.

What is the maximum percentage of recombinants when genes assort independently?

The maximum number of recombinants is 50% when genes assort independently.

What happens when two genes are on the same chromosome without crossing over?

When two genes are on the same chromosome without crossing over, only two allele combinations, the same as in the parent, are possible.

What is the parent genotype for two genes in the example provided?

The parent genotype for the two genes in the example provided is AaBb.
