1. For an individual with Type O blood, choose all possible blood types of their children.

• Type
• Type A
• Type B
• Type AB

2. Match the statement/condition on the left with the type of dominance relationship on the right. Answers can be used once, more than once or not at all.

Phenotype is a blending of the two alleles ................. Incomplete dominance

One allele will mask the other allele............................ Standard dominance -

Neither allele is fully dominant over the other.......... Both Incomplete and Co-

F1 phenotype shows both alleles................................ Co-dominance

F2 generation has three distinct phenotypes............ Incomplete dominance

3. Plant height in pea plants is controlled by a single gene. Tistallwhilet is short. Match the genotype on the left with possible progeny on the right. Note you are only given ONE genotype and not a cross. Choose all possible progeny for the genotype on the left.

A heterozygous individual can give rise to progeny either dominant or recessive depending on genotype of the other parent.

A heterozygous individual can give rise to progeny either dominant or recessive depending on genotype of the other parent.

A homozygous recessive individual can produce either dominant or recessive depending on genotype of the other parent.
