Independent Assortment | Process of Science | Quiz

1. Mendel's Second Law is also known as

The Law of Probablity.

The Law of Segregation.

The Law of Punnett.

The Law of Independent Assortment.

2. A pea plant that is heterozygous for two traits is called a

hybrid.

dualheterotype.

dihybrid.

dualhybrid.

3. Mendel found that many genetic traits sort independently of one another; thus the ratio of phenotypes seen for two characteristics is simply the mathematical product of the individual probabilities.

true

false

4. The term "testcross" is used to describe

an experiment used to validate a previously discovered finding.

an experiment to determine a new genetic ratio.

an experiment to determine the genetic compatibility of two species.

a model of the genotype of an organism.

5. The ratio of phenotypes expressed when a plant that is heterozygous for two traits is crossed with a plant that is homozygous recessive for both traits is

3:1

9:3:3:1

1:2:2:1
