Genetics Review

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 from the parents.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, one inherited from each parent.

Front

What is a dominant trait?

Back

A dominant trait is one that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A recessive trait is one that is only expressed in the phenotype when two copies of the allele are present.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

Who is known as the father of genetics?

Back

Gregor Mendel is known as the father of genetics for his work on inheritance patterns in pea plants.

Front

What is the genotype?

Back

The genotype is the genetic makeup of an organism, representing the alleles it possesses.

Front

What is the phenotype?

Back

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

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene, either dominant or recessive.

Front

What is a trait?

Back

A trait is a characteristic or feature of an organism that can be inherited.
