Question

1. which concept is considered an exception to mendels law of independent assortment?

a) crossing over
d) law of segregation
b) gene linkage
e) sex - linked traits
c) polyploidy

Explanation:

Mendel's law of independent assortment states that alleles of different genes assort independently during gamete formation. Gene linkage occurs when genes are located close together on the same chromosome and tend to be inherited together, thus not assorting independently. Crossing - over can reduce linkage but is not the exception itself. The law of segregation is a different Mendel's law. Polyploidy is about chromosome number and sex - linked traits are related to genes on sex chromosomes but not the main exception to independent assortment like linkage.

Answer:

B. gene linkage
