Mendelism and Inheritance

If two plants homozygous for a dominant tall gene are crossbred, what is the probability of a tall plant?

• 1/4

• 3/4

• 1/2

• 4/4

This is an example of what?

• Incomplete Dominance

• Co-Dominance

• Dominant Trait

• Heterozygote

What is an allele?

• One of a couple forms of a gene that arise from mutations

• A trait only found on the X chromosome

• Where DNA is found

• Physical form of an organism

If two heterozygous plants are crossbred, what is the ratio of the phenotypic results

• 3:1

• 4:1

• 9:1

• 2:2

This is a result of what?

• Incomplete Dominance

• Co-dominance

• Sex linked traits

• A little bit of red food dye

If a man who is not color blind has a son with a woman who is a carrier of colorblindness, what is the probability of their son being colorblind?

• 1/4

• 1/3

• 1/2

• 4/4

What is the phenotypic ratio of a dihybrid cross

• 1:2:1

• 3:4

• 1:4

• 9:3:3:1

What is meant by heterozygous?

• Consisting of two of the same alleles

• Consisting of two different alleles

• Consisting of only one allele

• Consisting of two chromosomes

Which of the following was not a complication of inheritance?

• Incomplete dominance

• Co-dominance
