Mendelian & Non-Mendelian Genetics

Front

What is a genotype where only recessive alleles were passed on from both parents for one trait?

Back

Homozygous Recessive

Front

What is a genotype where one dominant and one recessive allele was passed on from both parents for one trait?

Back

Heterozygous

Front

What is the term for the physical expression of a gene?

Back

Phenotype

Front

What is the genotype for a red flowered plant in incomplete dominance with a white flowered plant?

Back

100% of the offspring will have pink (RW) flowers.

Front

What are the genotypes for red, white, and speckled carnations in codominance?

Back

Red = RR, White = WW, Speckled = RW

Front

Define 'allele'.

Back

An allele is a variant form of a gene.

Front

What is the difference between dominant and recessive alleles?

Back

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

Front

What is Mendel's Law of Segregation?

Back

It states that during the formation of gametes, the two alleles for a trait segregate from each other.

Front

What is Mendel's Law of Independent Assortment?

Back

It states that alleles for different traits are distributed to gametes independently of one another.

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed.
