Genetics Day 7 Review

Front

What is incomplete dominance in genetics?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two alleles.

Front

What is the genotype of a red flowered plant in the context of incomplete dominance?

Back

RR (homozygous dominant) represents the red flowered plant.

Front

What is the genotype of a white flowered plant in the context of incomplete dominance?

Back

WW (homozygous recessive) represents the white flowered plant.

Front

What percentage of offspring will have pink flowers when RR is crossed with WW?

Back

100% of the offspring will have pink flowers (RW) due to incomplete dominance.

Front

What does a shaded square represent on a pedigree chart?

Back

A shaded square represents an affected male.

Front

What does a shaded circle represent on a pedigree chart?

Back

A shaded circle represents an affected female.

Front

What is the definition of homozygous recessive?

Back

Homozygous recessive refers to an organism that has two identical recessive alleles for a trait, such as rr.

Front

What is the genotype for a heterozygous organism?

Back

Aa is the genotype for a heterozygous organism, having one dominant and one recessive allele.

Front

What is a pedigree chart used for?

Back

A pedigree chart is used to track the inheritance of traits through generations in a family.

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 or characteristics.
