Which of the following genotypes would be considered homozygous recessive?

• RR

• Bb

• dd

• g

How can a Punnett square be used to predict the outcome of a genetic cross?

• By showing the possible genotypes of the offspring

• By determining the exact number of offspring

• By identifying the environmental factors affecting the offspring

• By calculating the age of the offspring

How does a Punnett square help in understanding Mendelian genetics?

• It predicts the exact number of offspring.

• It shows the possible genetic combinations and their probabilities.

• It determines the environmental impact on traits.

• It calculates the age of the offspring.
