Questions and Answers

What is the significance of Mendel's Law of Segregation in genetics?

  • It showcases the ratio of dominant to recessive traits in F2 generation.
  • It determines the probability of genetic traits in offspring.
  • It explains how alleles segregate during gamete formation. (correct)
  • It predicts the dominance of certain genes over others.

Why did Mendel focus on the F2 generation to determine the ratio of dominant to recessive traits?

  • It was in the F2 generation that recessive traits were more prevalent.
  • The F2 generation allowed for easier observation of genetic traits.
  • The F2 generation had a higher number of offspring for statistical accuracy. (correct)
  • The F2 generation had a more diverse genetic makeup for analysis.

What distinguishes a heterozygous organism from a homozygous organism?

  • Heterozygous organisms have a higher probability of expressing recessive traits.
  • Heterozygous organisms have two different gene copies, while homozygous organisms have two identical gene copies. (correct)
  • Heterozygous organisms have similar gene copies, while homozygous organisms have different gene copies.
  • Heterozygous organisms have two identical gene copies, while homozygous organisms have two different gene copies.
