Genetics- Monohybrid Punnett Squares

Front

Different forms of genes

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is the probability of heterozygous offspring from a monohybrid cross?

Back

The probability of heterozygous offspring (e.g., Gg) from a monohybrid cross is 50%.

Front

Which of the following is a genotype?

Back

Gg is a genotype, representing the genetic makeup of an organism.

Front

What phenotype do TT and Tt genotypes produce?

Back

Both TT and Tt genotypes produce a tall phenotype.

Front

What allele combination should go in the missing box?

Back

The missing box should contain Aa, representing a heterozygous genotype.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles inherited from parents.

Front

Define homozygous. Give an example.

Back

Homozygous refers to having two identical alleles for a particular gene, e.g., AA or aa.

Front

Define heterozygous. Give an example.

Back

Heterozygous refers to having two different alleles for a particular gene, e.g., Aa.

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 allele combinations from the parents.
