Heredity Flashcard

Front

Example of homozygous dominant genotype: AA, Aa, aa

Back

AA

Front

Example of heterozygous genotype: Aa, aa, AA

Back

Aa

Front

What type of dominance occurs when one allele completely dominates over another allele? (For example, if an organism has a freckles allele and a no freckles allele, then it will have freckles.)

Back

Complete Dominance

Front

Which type of dominance occurs when neither allele dominates over the other, but the phenotype is an intermediate of both alleles? (For example, if a red flower is mated with a white flower, their offspring would be pink)

Back

Incomplete dominance

Front

What type of dominance occurs when neither allele dominates over the other, but the phenotype is an expression of both alleles? (For example, If a brown cow is mated with a white cow, the offspring has both white & brown spots)
