1. What are Mendel’s Laws?

A Law of Segregation

B

C

Law of Independent assortment

Both Law of Segregation and Law of Independent Assortment

BACK TO QUESTION

Right!!!!!!!!• Both the Law of Segregation and the Law of

Independent Assortment are included in Mendel’s Law

• The Law of Segregation states that each allele segregates separately. One of each homologous chromosomes goes to each new cell.

• The Law of Independent Assortment states that in a dihybrid cross, each trait is independent of the other.
