What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Back

Homozygous refers to having two identical alleles for a particular gene, such as TT or tt.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as Tt.

What is the genotype?

Back

The genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is the phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even when only one copy is present, while recessive alleles only express their trait when two copies are present.

How many chromosomes do humans have?

Back

Humans have 46 chromosomes in each normal body cell.

Front

What is a monohybrid cross?

Back

A monohybrid cross is a genetic cross between parents that differ in a single trait.

Front

What is a dihybrid cross?

Back

A dihybrid cross is a genetic cross between parents that differ in two traits.

Front

What is the law of segregation?

Back

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