Questions and Answers

What is the result of crossing an organism showing homozygous dominant genotype with another showing homozygous recessive genotype?

  • Phenotypically diverse F1 generation
  • Homozygous F1 generation in genotype and phenotype
  • Heterozygous F1 generation in genotype and phenotype
  • Uniform F1 generation in genotype and phenotype (correct)

According to the law of segregation, how do alleles of each parent separate and pass on to offspring?

  • Both alleles of each parent always pass on to an offspring
  • Only one allele of each parent passes on to an offspring (correct)
  • The dominant allele of each parent passes on to an offspring
