Question 9

Which situation below would violate the law of independent assortment,as understood by Mendel?

Accepted Answer

A)  A plant breeder is able to create a true-breeding line that combines the alleles for white flowers and wrinkled peas. 
B)  A mutant gene can prevent pod formation altogether, thus preventing expression of the round or wrinkled pea alleles. 
C)  A gene for petal color does not affect the expression of a gene for petal number. 
D)  A gene for leaf shape is linked to a gene for petal number nearby on the same chromosome, so their alleles usually segregate together. 
E)  Combining certain alleles of different genes results in a plant that grows poorly.
