Punnett Square Practice

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 the letter 'G' represent in genetics?

Back

In genetics, 'G' typically represents a dominant allele, while 'g' represents a recessive allele.

Front

What is the genotype for a yellow plant if G = green and g = yellow?

Back

gg

Front

What allele combination should go in the missing box if the options are AA, Aa, aa, none of these?

Back

Aa

Front

What is the probability of heterozygous offspring when crossing two heterozygous parents?

Back

50%.

Front

What genotype would go in box 2 if the options are BB, Bb, bb?

Back

Bb.

Front

What is a genotypic ratio?

Back

A genotypic ratio is the ratio of different genotypes produced in a genetic cross.

Front

What is the genotypic ratio of the offspring from a monohybrid cross?

Back

1:2:1.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., GG or gg).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Gg).
