genetic inheritance

What is the expected phenotypic ratio of offspring from a monohybrid self-cross where both parents are heterozygous (Pp)?

• 1:1

• 3:1

• 1:2:1

• 9:3:3:1

In a monohybrid self-cross of a plant with genotype Rr (where R = red flowers, r = white flowers), what are the possible genotypes of the offspring?

• RR

• Rr

• rr

• all of the above

A Punnett square is used to predict the genotype and phenotype ratios of offspring in genetic crosses.

• True

• False

If a person with genotype Bb (brown eyes) performs a self-cross (Bb x Bb), there is a 25% chance that the child will have blue eyes.

• True

• False

A monohybrid self-cross of a plant with the genotype Tt (where T = tall and t = short) will result in a genotypic ratio of TT, Tt, and tt (____:____:____) respectively.
