Mendelian & Non-Mendelian Genetics

Front

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

Back

Homozygous Dominant

Front

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

Back

Heterozygous

Front

What is the genotype for a heterozygous dominant offspring when green peas (G) are dominant to yellow peas (g)?

Back

Gg

Front

What is the genotype for a homozygous dominant offspring when round (R) seeds are dominant to wrinkled (r) seeds?

Back

RR

Front

What type of inheritance is represented when both alleles in a genotype are expressed equally?

Back

Codominance

Front

Define 'allele'.

Back

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

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous has identical alleles (e.g., AA or aa), while heterozygous has different alleles (e.g., Aa).

Front

What is Mendelian genetics?

Back

Mendelian genetics is the study of how traits are inherited through the segregation and independent assortment of alleles.

Front

What is the principle of segregation?

Back

The principle of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the principle of independent assortment?

Back

The principle of independent assortment states that alleles for different traits are distributed to gametes independently of one another.
