Inheritance

Front

What is inheritance in genetics?

Back

Inheritance is the process by which genetic information is passed from parents to their offspring.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

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 does homozygous mean?

Back

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

Front

What does heterozygous mean?

Back

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

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present (e.g., T in Tt).

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present (e.g., tt).

Front

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the law of independent assortment?

Back

The law of independent assortment states that alleles for different traits are distributed to gametes independently of one another.

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.
