MM#7 Mendelian Genetics

Front

What is a heterozygous genotype?

Back

A genotype consisting of one dominant and one recessive allele, such as Rr.

Front

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

Back

Gg

Front

What is the genotype for a homozygous recessive offspring for dimples (D = dimples, d = no dimples)?

Back

dd

Front

If green is dominant over purple, what is the genotype for a purple individual?

Back

gg

Front

Define heterozygous in terms of alleles.

Back

A genotype where one dominant and one recessive allele is present.

Front

What does homozygous dominant mean?

Back

A genotype with two dominant alleles, such as GG.

Front

What does homozygous recessive mean?

Back

A genotype with two recessive alleles, such as gg.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup (e.g., GG, Gg, gg), while phenotype refers to the observable traits (e.g., green or yellow peas).

Front

What is the significance of dominant and recessive alleles?

Back

Dominant alleles mask the effect of recessive alleles in heterozygous genotypes.

Front

Provide an example of a homozygous dominant genotype.

Back

An example is AA or BB.
