Genetics Final Exam

What were the expected results of crosses b/w parents with contrasting traits?

• Co-Dominance

• Recessive

• Homozygous

• Blending

Is the P1 generation haploid or diploid?

• Haploid

• Diploid

Which is NOT one of Mendel's Laws?

• Law of Independent Assortment

• Law of Partial/Incomplete dominance

• Law of Dominance and Recessiveness

• Law of Segregation

How did Mendel find where the recessive trait went in F1 offspring?

• Test Cross

• Intercross

• Cross b/w P1 generation

What is an intercross?

• Cross b/w P1 Generation

• Cross b/w F1 Generation

• Test Cross

Since there are only two traits being tested for inheritance in the monohybrid cross, the chance that a gamete will have one of the two traits is:

• 1/2

• 1/4

• 1/16

• 3/4

Crosses involving true-breeding parental strains leads to only one outcome:

• heterozygosity

• homozygosity

Individuals who are homozygous for one or more genes can only produce _____ genetic gamete type.

• two

• one

• This cannot be determined without the genotypes

• 16

• four

Individuals who are heterozygous for one or more genes can produce at minimum _____ genetically different gamete types

• four

• one

• two

• This cannot be determined without the genotypes

What is a Dihybrid Cross?

• Crosses b/w two true breeding parents

• Crosses that involve two contrasting traits

• Crosses that involve one contrasting trait

• Crosses b/w two alleles that are absolutely linked
