Punnett Squares 3-19

Front

What are genotypes?

Back

Genotypes are the genetic makeup of an organism, represented by the combination of alleles (e.g., Aa, DD, Bb, yy).

Front

What are phenotypes?

Back

Phenotypes are the observable traits or characteristics of an organism, determined by its genotype.

Front

How are dominant alleles represented?

Back

Dominant alleles are represented by a capital letter.

Front

What does homozygous dominant mean?

Back

Homozygous dominant refers to having two identical dominant alleles for a trait (e.g., AA).

Front

What is the phenotype of a plant with genotype Tt?

Back

The phenotype is tall stem, as tall (T) is dominant over short (t).

Front

What does the letter 'T' represent in genetics?

Back

The letter 'T' represents the dominant allele for tall stem in a plant species.

Front

What does the letter 't' represent in genetics?

Back

The letter 't' represents the recessive allele for short stem in a plant species.

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.

Front

What is the purpose of a Punnett square?

Back

The purpose of a Punnett square is to determine the probability of an offspring inheriting particular traits from its parents.

Front

What does it mean if an organism is heterozygous?

Back

An organism is heterozygous if it has two different alleles for a specific trait (e.g., Aa).
