1.) You cross a pea plant with purple flowers to a plant with white flowers. The resulting offspring have a mixture of purple and white flowers. What were the possible genotypes of the parents if the purple allele is dominant (B) and the white allele is recessive (b)? (Hint: draw Punnett squares).
Parent 1: Bb, Parent 2: BB
Parent 1: BB, Parent 2: bb
Parent 1: bb, Parent 2: bb
Parent 1: Bb, Parent 2: bb
2.) Consider a diploid organism. What is the phenotypic ratio expected to be observed in the offspring produced by two homozygous recessive parents?
0 dominant: 1 recessive
1 dominant: 1 recessive
2 dominant : 1 recessive
3 dominant : 1 recessive
3.) Mendel’s law of Independent Assortment describes the independent movement of _______ into ______ during meiosis.
alleles of the same gene, gametes
alleles of different genes, gametes
alleles of different genes, the cytoplasm
No law was violated
Two diploid individuals, one homozygous and the other heterozygous at a particular gene, make babies. Which of the following statements about the offspring genotype is correct? (Hint: draw Punnett squares)
All offspring are heterozygotes
All offspring are homozygotes
1/2 of the offspring are homozygotes and 1/2 are heterozygotes
homozygotes and 3/4 are heterozygotes
