Genetics- Monohybrid Punnett Squares

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.

What does 'T' represent in genetics?

Back

In genetics, 'T' typically represents a dominant allele, which can express a trait when present.

Front

What does 't' represent in genetics?

Back

In genetics, 't' typically represents a recessive allele, which only expresses a trait when two copies are present.

Front

What is the genotype for a homozygous tall plant?

Back

The genotype for a homozygous tall plant is 'TT'.

Front

What is the genotype for a homozygous short plant?

Back

The genotype for a homozygous short plant is 'tt'.

Front

What is the genotype for a heterozygous tall plant?

Back

The genotype for a heterozygous tall plant is 'Tt'.

Front

What is the probability of obtaining a homozygous recessive offspring from a cross of Tt x Tt?

Back

The probability is 25%.

Front

What is the probability of obtaining a heterozygous offspring from a cross of Tt x Tt?

Back

The probability is 50%.

Front

What does it mean if an allele is dominant?

Back

A dominant allele is one that expresses its trait even when only one copy is present.

Front

What does it mean if an allele is recessive?

Back

A recessive allele is one that only expresses its trait when two copies are present.
