Question

The fact that all seven of the pea plant units studied by Mendel obeyed the principle of independent assortment most probably indicates which of the following? None of the traits obeyed the law of The diploid number of chromosomes in the All of the genes controlling the traits behaved as if they were on different chromosomes. The formation of gametes in plates occurs by mitosis only. Two cars of corn are crossed. One is homozygous for both the dominant alleles 'P' which cases kernels to be purple and the recessive alleles 'w' which cause kernels to be wrinkled. The other car is homozygous for the wild type alleles. What is the phonotype and genotype of the F1 generation? What phenotype would you expect to see in the F2 generation? What proportion of the F2 kernels would you expect to display each of these phenotypes?

Answer : (D) All of the genes controlling the traits behaved as if they were on different chromosomes.

According to law of independent assortment, the genes do not influence each other with regard to the sorting of alleles in to gametes. To obey the above condition it is necessary for all the genes controlling the traits behave as if they were on different chromosomes.
