. In common wheat, Triticum aestivum, kernel color is determined by multiply duplicated genes, each with an Rand an r allele. Any number of R alleles will give red, anda complete lack of R alleles will give the white phenotype.In one cross between a red pure line and a white pureline, the F2 was 6463 red and 641 white.a. How many R genes are segregating in this system?b. Show the genotypes of the parents, the F1, and the F2.c. Different F2 plants are backcrossed with the whiteparent. Give examples of genotypes that would give thefollowing progeny ratios in such backcrosses: (1) 1 red :1 white, (2) 3 red :1 white, (3) 7 red :1 white.d. What is the formula that generally relates thenumber of segregating genes to the proportion of redindividuals in the F2 in such systems?
