Law of Independent assortment
C
Both Law of Segregation and Law of Independent
Assortment

BACK TO QUESTION
7
Right!!!!!!!!

• Both the Law of Segregation and the Law of
  Independent Assortment are included in Mendels
  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.
