Genetics

Front

What does genotype refer to?

Back

The possible combination of alleles in a gene.

Front

How many alleles does an offspring receive from each parent to determine a specific trait?

Back

One allele from each parent.

Front

In a genetic cross of AA x aa, what is the genotype of all offspring?

Back

Aa.

Front

What is the phenotype of an organism with a blue color?

Back

Blue.

Front

What type of inheritance do Snapdragon flowers exhibit when they come in red, pink, and white?

Back

Incomplete Dominance.

Front

What is the definition of phenotype?

Back

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

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even in the presence of a recessive allele, while recessive alleles only express their trait when two copies are present.

Front

What is a homozygous genotype?

Back

A genotype consisting of two identical alleles for a particular gene.

Front

What is a heterozygous genotype?

Back

A genotype consisting of two different alleles for a particular gene.

Front

What is the purpose of a Punnett square in genetics?

Back

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