Mendelian & Non-Mendelian Genetics

Front

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

Back

Homozygous Recessive

Front

What are the different forms of a gene called?

Back

Alleles

Front

In some carnations, what are the genotypes for red, white, and speckled flowers exhibiting codominance?

Back

Red = RR, White = WW, Speckled = RW

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

Define 'Homozygous Dominant'.

Back

A genotype with two dominant alleles for a trait (e.g., GG).

Front

What is the definition of 'Phenotype'?

Back

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

Front

What is the principle of segregation in genetics?

Back

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

Front

What does 'Codominance' mean in genetics?

Back

A situation in which both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is the difference between 'Homozygous' and 'Heterozygous'?

Back

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