Question

QUESTION 2 When do genes violate the law of independent assortment? O when trisomy happens when mutations happen O when they are on the same chromosome and close together o when they come from the same parent

Answer 1

option C is the correct answer.

Linked genes violate the law of independant assortment.In linked genes they are located very close to each other on the same chromosome.They are more likely to be inherited as a pair.The segregation of alleles into gametes can be influenced by linkage.Here the genes are inherited as a unit unless recombination breaks them apart.Mendels law of independant assortment states that the genes do not influence each other with regard to the sorting of alleles into gametes;every possible combination of alleles for every gene is equally likely to occur.Genes that are loceted on seperate non-homologous chromosomes will always sort independantly.But each contains hundreds or thousands of gene organised linearly on chromosomes like beads on a string.The segregation of alleles into gametes can be influenced by linkage,in which genes that are located physically close to each other on the same chromosome are more likely to be inherited as a pair.However,because of the process of recombination or crossing over,it is possible for two genes on the chromosome to behave independently,or as if they are not linked.
