Biology Test Monohybrid Crosses

Front

What is a monohybrid cross?

Back

A monohybrid cross is a genetic cross between two individuals that differ in one trait, focusing on the inheritance of a single characteristic.

Front

What does it mean for an allele to be dominant?

Back

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

Front

What does it mean for an allele to be recessive?

Back

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

Front

What is the genotype of an individual with two identical alleles?

Back

The genotype is homozygous.

Front

What is the genotype of an individual with two different alleles?

Back

The genotype is heterozygous.

Front

What is the phenotypic ratio expected from a monohybrid cross of two heterozygous parents?

Back

The expected phenotypic ratio is 3:1.

Front

Who is known as the Father of Genetics?

Back

Gregor Mendel is known as the Father of Genetics.

Front

What is the significance of a Punnett square?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What does the term 'allele' refer to?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an individual, while phenotype refers to the observable traits.
