Punnett Squares

Front

What do dominant alleles represent in genetics?

Back

Dominant alleles are represented by a capital letter.

Front

What is the term for an organism with two different alleles for a trait?

Back

Heterozygous.

Front

What is the probability of a blue-eyed baby from two brown-eyed parents (Bb)?

Back

25%.

Front

In genetics, what does 'T' and 't' represent in terms of height?

Back

'T' = tall, 't' = short.

Front

What is a Punnett square?

Back

A graph used to predict the possible genotypes of offspring in a given cross.

Front

What do recessive alleles represent in genetics?

Back

Recessive alleles are represented by a lowercase letter.

Front

What is the term for an organism with two identical alleles for a trait?

Back

Homozygous.

Front

If a parent has genotype 'TT', what are the possible genotypes of their offspring?

Back

All offspring will be 'T' (homozygous dominant).

Front

What is the expected genotype ratio from a monohybrid cross of two heterozygous parents (Tt x Tt)?

Back

1 TT : 2 Tt : 1 tt.

Front

What does a genotype of 'Bb' indicate?

Back

The organism has one dominant allele (B) and one recessive allele (b).
