Front

What is Hemophilia?

Back

A disorder related to blood clotting wherein the gene that codes for an important protein necessary for blood clotting is missing.

Front

What is the percentage chance of having a daughter who is a carrier of hemophilia if one parent is a carrier?

Back

50%.

Front

What is Heredity?

Back

The passing of inherited traits from parents to offspring.

Front

What does the Law of Incomplete Dominance state?

Back

Front

What is Genetics?

Back

The study of heredity and the variation of inherited characteristics.

Front

What is a genotype?

Back

The genetic constitution of an individual, represented by alleles.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is codominance?

Back

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