7.5 Linked Genes, Crosses and Crossing Over Flashcards
1
Q
The Law of Independent Assortment states what?
A
The alleles of a gene controlling one trait assort independently of alleles of another gene controlling a different trait.
2
Q
What is linkage?
A
When two or more genes are located on a single chromosome and are inherited together.
3

A
Inherited together.
4

A
Mendel’s Law
5

A
A normal event that results in the genetic exchange between non-sister chromatids.
