Module 7 Test Prep (Genetics, Inheritance, Punnett Squares)

Who is considered the "Father of Genetics?"

• Gregor Mendel

• Robert Hooke

• Antony van Leeuwenhoek

• Coach Patterson

Using the information from this Punnet square, what percentage (%) of the kittens born to these parents would have the sex-linked trait of colorblindness?

• 0%

• 25%

• 50%

• 100%

Which Punnett squares correctly calculate the genetic ratios between a homozygous parent and a heterozygous parent?

• 
• 
• 
• 
• 

According to the Punnett square, what are the genotypes of the parents?

• BB & bb

• bb & bb

• BB & Bb

• Bb & bb

Based on the random segregation and distribution of alleles during meiosis, which potential offspring from this cross would have the alleles aaBb?

• 12

• 15

• 1

• 4

• 8

Use a Punnett square to determine which of these statements is NOT true for the sex-linked trait of colorblindness.

• If the father is colorblind and the mother is not, then all sons are not colorblind.

• If the mother is colorblind and father is not, then all sons will be colorblind.

• If the mother is colorblind and the father is not, then all daughters will be colorblind.

• If the father is colorblind and the mother is not, then all daughters are not colorblind, but will be carriers.

Which genotype illustrates codominance of alleles that control blood type in humans?

• ii

• I^Ai

• I^AI^B

• I^BI^B

Which of the following are examples of incomplete dominance?

• Two white mice mate and produce only white offspring.

• A white rose bush is cross-pollinated with a red rose bush which results in a pink rose bush.

• A brown dog and a black dog mate and produce offspring with black fur.

• A black cat and a white cat mate and produce offspring with black and white spots.

• A child with wavy hair is born to parents, one of whom has straight hair and one of whom has curly hair.

When Mendel worked with pea plants, he noticed that some traits, like round seeds, seemed to hide other traits, like wrinkled seeds. What do we call the trait that hides or masks another trait?

• Dominant trait

• Incomplete Dominance

• Recessive trait

• DNA replication

A certain species of chicken has three different alleles available for feather color. The F^W allele results in white feathers, the F^B allele results in black feathers and the F^r allele results in red feathers. Both the F^W allele and F^B allele are dominant over the F^r allele, but the F^W and F^B alleles demonstrate incomplete dominance with each other.

Which of the following represents a cross between a white hen and a black rooster?

• FWFB × FB Fr

• FW FW × FB Fr

• FW FW × Fr Fr

• F^W F^r × F^B F^W
