Two plants in a cross were each heterozygous for two gene pairs (Ab/aB) whose loci are linked and 25 mu apart. Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring.

Hello everyone here we have a question that's asking us if a test cross yields the following results. Parental 1100 for parental to 1, recombination 1 134 and were competent to 155. What is their recombination frequency now? To calculate our recombination frequency, we're going to use a formula and that formula is R. F. Equals number of our continent over total number of offspring Times 100 to get a percentage. So in this case we are going to have Plus 155 over 1104 plus 1037 plus 1 Plus 1 55 times 100. So we'll have over times Equals 11.89%. So our correct option here is the 11.89%. Thank you for watching. Bye.
