Assume you are performing a cross between a plant that is heterozygous for the dominant traits red flowers and wrinkled seeds, with a plant that is homozygous for the recessive traits white flowers and smooth seeds. assume the alleles are r for red flowers, r for white flowers, w for wrinkled seeds, and w for smooth seeds. the offspring of this cross show the following phenotypes:
43 red flowers and wrinkled seeds
7 red flowers and smooth seeds
9 white flowers and wrinkled seeds
41 white flowers and smooth seeds

what are the traits of the recombinant offspring in terms of flower color and seed shape? explain how you know that these offspring are recombinant. what alleles would you expect to see in the individual chromosomes of each parent before and after crossing-over takes place? what is the recombination frequency? what is the distance between the genes in map units?

hint: to calculate the recombination frequency, or the percentage of recombinants in the population, use this equation: total number of recombinant offspring / total number offspring = recombinant frequency. then use that number to calculate the distance in map units between the genes. use this equation: distance = recombination frequency x 100.
