What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic makeup of offspring from two parents based on their genotypes.

Front

What does 'F' represent in a Punnett Square?

Back

'F' typically represents a dominant allele in genetic notation.

Front

What does 'f' represent in a Punnett Square?

Back

'f' typically represents a recessive allele in genetic notation.

Front

What is the purpose of using a Punnett Square?

Back

The purpose is to determine the probability of an offspring inheriting particular traits from its parents.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles inherited from the parents.

Front

What is a phenotype?

Back

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

Front

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

Back

25%.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., FF or ff).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Ff).

Front

What is the probability of getting a dominant phenotype from a cross between a homozygous dominant (FF) and a homozygous recessive (ff)?

Back

100%.
