Mendelian Genetics and Punnett Squares

Front

What is a dominant trait in Mendelian Genetics?

Back

A trait or characteristic that will appear in the offspring if one or both of the parents contributes it.

Front

What type of inheritance occurs when two alleles blend together?

Back

Incomplete Dominance

Front

What tool can be used to calculate the probability of an offspring's genotype?

Back

Punnett square

Front

What does Tt represent in genetics?

Back

Heterozygous

Front

If both parents are heterozygous for brown hair (dominant) and blond hair (recessive), what is the probability that their offspring will have blond hair?

Back

25%.

Front

Define homozygous dominant.

Back

An organism with two identical dominant alleles for a trait.

Front

Define homozygous recessive.

Back

An organism with two identical recessive alleles for a trait.

Front

What is co-dominance?

Back

A form of inheritance where both alleles in a heterozygote are fully expressed.

Front

What is the purpose of a Punnett square?

Back

To predict the genotypes of offspring from parental genotypes.

Front

What does it mean if an organism is heterozygous?

Back

It has two different alleles for a specific gene.
