The study of how traits are passed from parent to child. What is genetics?

A different form of the same gene. What is an allele?

The expressed trait (represented by a capital letter). What is the dominant trait (dominant gene)?

An organism that has 1 dominant allele and 1 recessive allele. What is a heterozygote (heterozygous)?

Genotype referred to as being “pure.” What is homozygous?

What are purple flowers? When Mendel crossed a true breeding purple-flowered plant and a true breeding white-flowered plant, all of the F1 generation plants had this color of flower. What are purple flowers?

The probability that two heterozygous plants for tallness will produce a short plant. What is 25%?

What is the Law of Independent Assortment? This law of Mendel’s states that the genes for two different characteristics are inherited separately. What is the Law of Independent Assortment?

The genotype of a person who does not have a recessive trait, but one of his/her parents does. What is heterozygous?

Separation of alleles during the formation of gametes. What is the Law of Segregation?

In human blood typing, this allele acts as the recessive allele. What is the O (i) allele?

What is polygenic inheritance? A trait, such as eye or skin color, which is controlled by two or more genes. What is polygenic inheritance?

What is incomplete dominance? This type of inheritance forms a heterozygote that displays a blending of the two homozygous phenotypes. What is incomplete dominance?

An example of this type of inheritance pattern. What is codominance?

Human blood type is an example of this type of inheritance. What are multiple alleles?

Genotype for males. What is XY?

Sex chromosome that contains the most genes. What is the X chromosome?

An individual who do not express a disorder or trait but can pass the disorder or trait on to his/her offspring. What is a carrier?

The probability that a man with hemophilia and a carrier woman will have a child (of either sex) with hemophilia. What is 50% (½)?

The percent chance that a boy will be color blind if his father is color blind and his mother is normal sighted. What is 0%?

This type of trait does not show when paired with a dominant trait. What is recessive?

Genes are carried on these. What are chromosomes?

Used to determine the probable outcome(s) of a cross. What is a Punnett Square?

Breeding a recessive phenotype with a dominant phenotype to determine the dominant individual’s genotype. What is a test cross?

This blood type is the universal recipient. What is AB?
