Heredity TEST Review

Front

What is a heterozygous genotype?

Back

A genotype consisting of two different alleles, such as Aa.

Front

What is a recessive allele?

Back

A trait that is hidden whenever a dominant allele is present.

Front

How are dominant alleles represented?

Back

Dominant alleles are expressed with capital letters.

Front

What is a Punnett Square?

Back

A tool used to predict the probability of genotype combinations from a genetic cross.

Front

What does the genotype RR represent?

Back

It represents a homozygous dominant trait, such as Red Fish.

Front

What does the genotype RB represent?

Back

It represents a heterozygous trait, such as Red & Blue Fish.

Front

What is the probability of offspring being all red from a cross of RR x RB?

Back

50%.

Front

What is a homozygous recessive genotype?

Back

A genotype consisting of two identical recessive alleles, such as aa.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed.

Front

What is the purpose of meiosis in heredity?

Back

Meiosis is the process that produces gametes with half the number of chromosomes.
