Questions and Answers

What is the purpose of a Punnett Square?

  • To identify the sex of an offspring
  • To determine the genetic makeup of an organism
  • To classify the species of an organism
  • To predict the probability of a trait in offspring (correct)
  • What is represented by the columns in a Punnett Square?

  • The alleles contributed by the male parent
  • The possible genotypes of the offspring
  • The alleles contributed by the female parent (correct)
  • The environmental factors affecting the trait
  • What is the significance of the uppercase and lowercase letters in the Punnett Square?

  • They represent the sex of the offspring
  • They indicate the dominant and recessive alleles (correct)
  • They show the probability of the trait being expressed
  • They are used to label the columns and rows
  • What is the result of crossing a Bb individual with a bb individual?

    Study Notes

    Punnett Square Analysis

    • The Punnett Square is incomplete, with missing alleles.
    • The options for the missing alleles are b, b, B, B, B, or b.
    • Determining the correct missing alleles is crucial for predicting the traits of the offspring.

    Pea Plant Traits

    • The dominant trait for pea color is related to the traits shown in the picture.
    • The options for the dominant trait are green pea pods, yellow pea pods, a mix of green and yellow, or none of the above.
    • Understanding the dominant trait is essential for predicting the expression of pea color in the offspring.
