Front

What type of allele shows its effect even if only one parent passes it on?

Back

Dominant

Front

What do we call a gene that has more than two variations?

Back

Multiple alleles

Front

What type of trait shows only if both parents pass it on?

Back

Recessive

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous genotypes have identical alleles, while heterozygous genotypes have different alleles.

Front

What is the principle of segregation in genetics?

Back

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

Front

What is a phenotype?

Back

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

Front

What is a genotype?

Back

The genetic constitution of an individual, specifically the alleles present for a particular gene.

Front

What is the significance of Punnett squares in genetics?

Back

Punnett squares are used to predict the genotypes and phenotypes of offspring from a genetic cross.
