Back

Starch is the polysaccharide used by plants to store glucose.

Front

What is the percentage of homozygous recessive offspring in a typical Mendelian cross?

Back

50% of the offspring will be homozygous recessive.

Front

Define heterozygous in terms of alleles.

Back

A heterozygous genotype has one dominant and one recessive allele for a trait.

Front

What is the genotype for homozygous dominant?

Back

The genotype for homozygous dominant is represented as AA.

Front

What is heredity?

Back

Heredity is the passing on of traits from parents to offspring.

Front

What is the role of glycogen in animals?

Back

Glycogen is the polysaccharide used by animals to store glucose.

Front

Define genotype.

Back

Genotype refers to the genetic makeup of an organism, represented by alleles.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What does a Punnett square illustrate?

Back

A Punnett square illustrates the possible genetic combinations from a cross between two parents.

Front

What is the significance of the allele in genetics?

Back

An allele is a variant form of a gene that can result in different traits.
