No, the two genes are present in different chromosome. Only homologous chromosomes are pairs with each other and crossing over take place in meiosis I. Two chromosome 11,11 are homologous with each other and two chromosome 16,16 are homologous and they pair with each other. The chromosome 11 and 16 are not homologous so they not pair with each other.

Genes A and B are located 10cM from each other on a chromosome. Gene C is located 25cM from gene A and 15cM from gene B. Assuming that I = 0, what is the probability that the trihybrid ABC/abc will produce an ABC gamete? Genes A and B are located 10cM from each other on a chromosome. Gene C is located 25cM from gene A and 15cM from gene B. Assuming that I = 0, what is the probability that...

In beetles, a gene coding for body color and a gene coding for bristle length are located on the same chromosome. Black (B) is dominant over grey body (b) and long bristles (s) are recessive to short bristles (S). A beetle that is heterozygous for black body and short bristles is mated with one that has a grey body and long bristles. What are the genotypes of the parents? ____________ ____________ Assume that the B allele is linked with the...

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...
