Complete dominance Review

Front

What is complete dominance in genetics?

Back

Complete dominance occurs when the phenotype of the heterozygote is indistinguishable from that of the homozygous dominant individual.

Front

What does a Punnett square represent in genetics?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles (e.g., AA).

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of one dominant allele and one recessive allele (e.g., Aa).

Front

Define recessive allele.

Back

A recessive allele is an allele whose trait is only expressed in the absence of a dominant allele.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

Who is known as the father of genetics?

Back

Gregor Mendel is known as the father of genetics for his work on inheritance patterns in pea plants.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic constitution of an individual, while phenotype refers to the observable traits.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that expresses its trait even in the presence of a recessive allele.

Front

What is the significance of the F1 generation in genetics?

Back

The F1 generation is the first filial generation, resulting from a cross between two parental (P) generations.
