Front

What is Codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is Incomplete Dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a new phenotype that is a blend of the two.

Front

What are the possible genotypes for type B blood?

Back

The possible genotypes for type B blood are I^BI^B and I^Bi.

Front

What is the expected phenotype of offspring from a WW and ww cross?

Back

All offspring will have white hair.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that masks the effect of another allele when both are present in a heterozygote.

Front

What is the probability of a child having type O blood if both parents have type AB blood?

Back

0%.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, specifically the alleles present at a particular gene locus.

Front

What is a recessive allele?

Back

A recessive allele is one that is masked by the presence of a dominant allele and only expresses its trait when two copies are present.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a particular gene, one inherited from each parent.
