What is a hybrid in genetics?

Back

A hybrid refers to an organism that has two different alleles for a specific gene, making it heterozygous.

Front

What does homozygous recessive mean?

Back

Homozygous recessive refers to having two identical recessive alleles for a trait, such as 'nn', 'ww', or 'gg'.

Front

What does homozygous mean?

Back

Homozygous means having two identical alleles for a specific gene, such as 'TT' or 'tt'.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, such as blue eyes or curly hair.

Front

What is a Punnett square?

Back

A Punnett square is a tool used in genetics to predict the possible genotypes of offspring from a cross between two parents.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, representing the alleles it carries.

Front

What is the difference between dominant and recessive alleles?

Back

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

Front

What does heterozygous mean?

Back

Heterozygous means having two different alleles for a specific gene.

Front

What is an allele?

Back

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

Front

What is the purpose of a genetic cross?

Back

The purpose of a genetic cross is to determine how traits are inherited and to predict the genetic makeup of offspring.
