Question 1

What is probability?

Answer 1

The likelihood that a particular event will occur

Question 2

If each F1 plant had one tall allele and one short allele (Tt), what is the ratio of gametes produced would carry the short allele?

Answer 2

1/2

Question 3

What ratio showed up constantly in mendels experiments?

Answer 3

3 dominant : 1 recessive

Question 4

What is homozygous?

Answer 4

Organisms that have 2 identical alleles for a particular gene (TT) or (tt)

Question 5

What is heterozygous?

Answer 5

Organisms that have two different alleles for the same gene. (Tt)

Question 6

What is genotype?

Answer 6

Genetic makeup (TT Tt tt). Is inherited.

Question 7

What is phenotype?

Answer 7

Physical traits (tall or short). Formed as a result of environment and genotype.

Question 8

What is the principle of independent assortment?

Answer 8

States that genes for different traits can separate independently during formation of gametes.

Question 9

What do Punnett squares do?

Answer 9

Use mathematical probability to help determine the genotype and phenotype combinations in genetic crosses
