Monohybrid Punnett Square

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses (e.g., BB, Bb, bb).

Front

What does the letter 'T' represent in a Punnett square?

Back

In a Punnett square, 'T' typically represents the dominant allele for a trait, such as tallness in plants.

Front

What does the letter 't' represent in a Punnett square?

Back

In a Punnett square, 't' typically represents the recessive allele for a trait, such as shortness in plants.

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

What is the phenotype of an organism with genotype 'BB'?

Back

The phenotype of an organism with genotype 'BB' is typically dominant, such as tall in plants.

Front

What is the phenotype of an organism with genotype 'bb'?

Back

The phenotype of an organism with genotype 'bb' is typically recessive, such as short in plants.

Front

What is the purpose of filling in a Punnett square?

Back

Filling in a Punnett square helps visualize the possible genetic combinations from a genetic cross.

Front

If one parent is 'Bb' and the other is 'bb', what are the possible genotypes of the offspring?

Back

The possible genotypes of the offspring are Bb and bb.

Front

What is the expected ratio of phenotypes in a monohybrid cross between two heterozygous parents (Bb x Bb)?

Back

The expected phenotype ratio is 3:1 (3 dominant: 1 recessive).

Front

What allele combination would go in box 1 if the parents are 'BB' and 'bb'?

Back

The allele combination in box 1 would be Bb.
