MENDELIAN GENETICS

Front

What are recessive alleles?

Back

Recessive alleles are represented by lowercase letters and are less likely to be expressed in the phenotype unless two copies are present.

Front

What type of allele is less likely to show up in offspring?

Back

Recessive allele.

Front

What do we call the observable traits resulting from a genotype?

Back

Phenotype.

Front

How are dominant alleles represented?

Back

Dominant alleles are represented by capital letters.

Front

If a pea plant is homozygous recessive for height, how are its alleles represented?

Back

tt.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a trait, such as TT or tt.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a trait, such as Tt.

Front

What is the principle of segregation?

Back

The principle of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from a genetic cross.
