Unit 5 Check 2: Non-Mendelian Genetics

Front

What is Incomplete Dominance?

Back

A type of inheritance where two alleles blend together to create a new phenotype, such as a pink flower from red (RR) and white (WW) parents.

Front

What is Co-Dominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is Mendelian Inheritance?

Back

A type of inheritance that follows the laws of Gregor Mendel, where traits are determined by dominant and recessive alleles.

Front

What does Homozygous mean?

Back

Having two identical alleles for a particular gene, such as AA or aa.

Front

What is a Pedigree?

Back

A diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

What is the genotype for a person with a recessive trait?

Back

The genotype would be homozygous recessive (e.g., gg).

Front

What are the blood types in humans?

Back

A, B, AB, and O are the four main blood types, determined by the presence or absence of antigens.

Front

What is the relationship between blood type A and blood type O?

Back

Blood type A is codominant with blood type B, while blood type O is recessive.

Front

What is the phenotype of a snapdragon flower with genotype RW?

Back

The phenotype is pink, resulting from incomplete dominance between red (RR) and white (WW) flowers.

Front

What is the purpose of using pedigrees in genetics?

Back

To track traits and inheritance patterns within families.
