What are the possible alleles a parent with genotype GgBb could donate to their gametes?

Back

GB, Gb, gB, gb

Front

In a species of plant, if purple (P) is dominant to white (p), what is the probability of an offspring being purple if both parents are heterozygous?

Back

100%

What is NOT a possible genotype for someone with type B blood?

Back

Front

What type of inheritance is determined by multiple genes and can show a range of traits?

Back

Polygenic traits

Using a dihybrid cross, what is the probability of the offspring being tall and white if the ratio is 9:3:3:1?

Back

Front

Define genotype.

Back

The genetic constitution of an individual, represented by alleles.

Front

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a Punnett Square used for?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What is codominance?

Back

A form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

A form of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.
