Mendel, Heredity & Complex Patterns of Inheritance

Front

What is incomplete dominance in genetics?

Back

Incomplete dominance is a type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What color flowers result from crossing a red flower (RR) with a white flower (rr) in snapdragons?

Back

The flowers that are Rr will be pink.

Front

What does it mean if an organism has two X chromosomes?

Back

It means the organism is biologically female.

Front

What is the term for the combination of alleles an organism has?

Back

Genotype.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What type of inheritance occurs when two alleles blend together?

Back

Incomplete dominance.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What is co-dominance in genetics?

Back

Co-dominance is a type of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

If a plant has the genotype Mm, what can we say about its alleles?

Back

The plant is heterozygous, having one dominant allele (M) and one recessive allele (m).
