Genetics and Heredity

Front

What is the role of DNA in genetics?

Back

To store genetic information.

Front

What is a dominant trait?

Back

A trait that is expressed when at least one dominant allele is present.

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another allele, resulting in a new phenotype.

Front

Where are the parent alleles written in a Punnett square?

Back

Outside of the boxes (top and left side).

Front

What describes a dominant allele?

Back

An allele that is expressed when present.

Front

What is a recessive allele?

Back

An allele that is masked by a dominant allele and is only expressed in homozygous form.

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by alleles.

Front

What is a phenotype?

Back

The observable characteristics or traits of an organism.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed.

Front

What is a Punnett square used for?

Back

To predict the genotypes and phenotypes of offspring from parental crosses.
