NGSS.HS-LS3-2

What is the criteria for a trait to be inherited by basic Mendelian rules?

• coded by a single gene

• only two alleles

• more than two phenotypes for the trait

• multiple genes interact to express the trait

In each case where Mendel crossed true breeding plants as parents, the offspring displayed only one of the two traits seen in the parents. This observation supports Mendel's principle of _________.

• segregation

• independent assortment

• dominance

• inheritance

Principle that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together.

• Independent Assortment

• Segregation

• Dominance

• Heredity

The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent passes to an offspring is Mendel's principle of:

• Independent Assortment

• Dominance

• Segregation

• Genetics

Genotype of identical alleles (Ex: HH or hh).

• phenotype
• homozygous
• heterozygous
• paleozygous
