Punnett Squares-Genetics Quiz

Which best explains why offspring created through sexual reproduction have greater variation than those created through asexual reproduction?

• Offspring created through sexual reproduction carry the traits of only the most dominant parent.

• Offspring created through sexual reproduction carry the traits from more than one generation of parents.

• Offspring created through asexual reproduction carry the traits from more than two separate parents.

• Offspring created through asexual reproduction carry the traits from two separate individual parents

Matt’s eye color is different from his father’s eye color. Which statement best explains this occurrence?

• The DNA regulating Matt’s eye color is identical to his mother’s DNA.

• Most of the DNA regulating Matt’s eye color is inherited from his father.

• Most of the DNA regulating Matt’s eye color is inherited from his mother.

• The DNA regulating Matt’s eye color is a unique combination of both of his parents’ DNA

Why do offspring that result from sexual reproduction most likely have greater variation than offspring that result from asexual reproduction?

• In sexual reproduction, half of the genes come from each parent, allowing for greater variability.

• In asexual reproduction, half of the genes come from each parent, allowing for greater variability.

• In sexual reproduction, the offspring result from budding, allowing for greater variability.

• In asexual reproduction, the offspring result from fertilization, allowing for greater variability.

A scientist noticed that all of the offspring of the yeast fungus are identical to the parent. However, the offspring of a cat all look different. What most likely caused this to occur?

• Yeast produced offspring through asexual reproduction, while the cat produced offspring through sexual reproduction.

• Yeast produced offspring through sexual reproduction, while the cat produced offspring through asexual reproduction.

• Both yeast and the cat produced offspring through asexual reproduction.

• Both yeast and the cat produced offspring through sexual reproduction.

The Punnett square below shows phenotypes and genotypes for a cross between two parent plants. Why will all of the F1 generation be tall?

• Both alleles for plant height are dominant.

• Both alleles for plant height are recessive.

• The allele for tall height is dominant, while the allele for short height is recessive.

• The allele for tall height is recessive, while the allele for short height is dominant.

The principle of __________ states that siblings can receive different genes from their parents.

• Heredity

• Genetic Variation

• Independent Assortment

• Meiosis

The Punnett Square below shows the genotypes of Amelia’s parents. If R represents the dominant gene for straight hair and r represents the recessive gene for curly hair, which statement best explains how Amelia was born with curly hair?

• She received two recessive genes.

• She received two dominant genes.

• She received one dominant and one recessive gene.

• She received one dominant and two recessive genes.

The diagram below shows the offspring of a parental cross for a specific trait. What can be predicted about the parents' genotypes?

• Both parents are heterozygous for the trait.

• Both parents are homozygous recessive for the trait.

• One parent is homozygous dominant for the trait and one parent is heterozygous for the trait.

• One parent is homozygous recessive for the trait and one parent is heterozygous for the trait.
