Genetics

Front

What is the genotypic ratio?

Back

The ratio of different genotypes produced in offspring from a genetic cross, typically expressed in terms of homozygous dominant, heterozygous, and homozygous recessive individuals.

Front

What is a homozygous dominant genotype?

Back

A genotype consisting of two identical dominant alleles (e.g., BB) for a specific trait.

Front

What is a heterozygous genotype?

Back

A genotype consisting of one dominant and one recessive allele (e.g., Bb) for a specific trait.

Front

What is a homozygous recessive genotype?

Back

A genotype consisting of two identical recessive alleles (e.g., bb) for a specific trait.

Front

What is a monohybrid cross?

Back

A genetic cross between individuals that differ in one trait, typically involving one pair of contrasting traits.

Front

What is the phenotypic ratio?

Back

The ratio of different phenotypes (observable traits) produced in offspring from a genetic cross.

Front

How many alleles does an offspring receive from each parent?

Back

One allele from each parent, resulting in a pair of alleles for each trait.

Front

If a homozygous dominant (WW) horse is crossed with a homozygous recessive (ww) horse, what fraction of the offspring will have white hair?

Back

All offspring will have white hair (100% WW).

Front

What does the term 'allele' refer to?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the purpose of a Punnett square?

Back

A Punnett square is a diagram used to predict the genotypes and phenotypes of offspring from a genetic cross.
