The rate of crossing over between two linked genes (r and w) is 0.44. The following cross is carried out: [tex]Rr Ww \times rr ww[/tex]. What percent of the gametes of the [tex]Rr Ww[/tex] parent are recombinant gametes?

Note: If your answer is 5 percent, just type 5.

Answer :

The rate of crossing over between two linked genes (r and w) is 0.44. The following cross is carried out: Rr Ww × rr ww. 44% of the gametes produced by the Rr Ww parent will be recombinant gametes.

To determine the percentage of recombinant gametes in the Rr Ww parent, we need to consider the two genes (r and w) and the rate of crossing over between them.

The rate of crossing over, given as 0.44, represents the proportion of gametes that undergo recombination. Since recombination involves the exchange of genetic material between the homologous chromosomes, it leads to the formation of new combinations of alleles.

In the given cross (Rr Ww × rr ww), the Rr Ww parent is heterozygous for both genes. During meiosis, crossing over can occur between the r and w genes on homologous chromosomes. If crossing over occurs, it results in the formation of recombinant gametes that carry different combinations of alleles compared to the parental chromosomes.

Since the rate of crossing over is 0.44, it means that 44% of the gametes produced by the Rr Ww parent will be recombinant gametes. This can be calculated by converting the rate to a percentage. Therefore, the percent of recombinant gametes in the Rr Ww parent is 44%.
