Monohybrid Punnett Squares (2024)

Front

What does T represent in a monohybrid cross where T=Tall and t=short?

Back

T represents the dominant allele for tallness.

Front

What is the genotypic ratio in a monohybrid cross involving one homozygous dominant and one homozygous recessive parent?

Back

1:2:1

Front

What is a Punnett square used for in genetics?

Back

A Punnett square is used to predict the traits of offspring based on the genotypes of the parents.

Front

Define genotype.

Back

Genotype refers to the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is the phenotype for the genotype Bb?

Back

The phenotype for Bb is Blue Chicken.

Front

What does heterozygous mean?

Back

Heterozygous means having two different alleles for a particular gene.

Front

What is the phenotypic ratio in a monohybrid cross?

Back

The phenotypic ratio in a monohybrid cross is typically 3:1.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the purpose of using a Punnett square?

Back

The purpose of using a Punnett square is to visualize the possible genetic combinations from a cross.

Front

What does homozygous mean?

Back

Homozygous means having two identical alleles for a particular gene.
