Question 1

How can we use probability to predict traits

Answer 1

Punnett squares use math probability to help predict the genotype and phenotype combinations in genetic crosses

Question 2

How do alleles segregate when more than one gene is involved?

Answer 2

The principle of independent assortment states that genes for different traits can segregate independently during formation of gametes

Question 3

What did Mendel contribute to our understanding of genetics?

Answer 3

Mendel’s Principles of Heredity, observed through patterns of inheritance, form the basis of modern genetics.

Question 4

Probability

Answer 4

The mathematical likelihood that a particular event will occur

Question 5

Homozygous

Answer 5

Organisms that have two of the same alleles for a gene

Question 6

Heterozygous

Answer 6

Organisms that have two of different alleles for a gene

Question 7

Phenotype

Answer 7

Physical Traits. “Pheno” = to show

Question 8

Genotype

Answer 8

Genetic makeup “Geno” = race, kind

Question 9

Punnett Square

Answer 9

Uses math probability to predict genotype and phenotype combinations in genetic crosses

Question 10

Independent Assortment

Answer 10

Genes for different traits can segregate independently during the formation of gametes
