Punnett Square

Front

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.

Front

What does homozygous mean?

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.

Front

What is a genotype?

Back

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

Front

What is a phenotype?

Back

A phenotype is the physical expression or characteristics of a genotype, such as height or eye color.

Front

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is the probability of getting a homozygous recessive offspring from two heterozygous parents (Tt)?

Back

The probability is 25%.

Front

What does the letter 'T' represent in genetics?

Back

In genetics, 'T' typically represents the dominant allele for a trait, such as tallness.

Front

What does the letter 't' represent in genetics?

Back

In genetics, 't' typically represents the recessive allele for a trait, such as shortness.

Front

If a tall plant (Tt) is crossed with a short plant (tt), what are the possible genotypes of the offspring?

Back

The possible genotypes are Tt and tt.
