Genetics and Patterns of Inheritance

Explain why a heterozygous individual with incomplete dominance does not show the dominant trait completely.

• The dominant allele is not strong enough to mask the recessive allele.

• Both alleles are expressed equally.

• The alleles blend to produce a new phenotype.

• The recessive allele is stronger than the dominant allele.

Describe a scenario where complete dominance is observed in a genetic cross.

• A red flower and a white flower producing pink offspring

• A black chicken and a white chicken producing speckled offspring

• A tall plant and a short plant producing tall offspring

• A blue-eyed parent and a brown-eyed parent producing a child with green eyes
