Mendelian & Non-Mendelian Genetics

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles inherited from its parents.

Front

What is a homozygous recessive genotype?

Back

A homozygous recessive genotype consists of two recessive alleles for a trait, represented as 'aa', 'bb', etc.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two dominant alleles for a trait, represented as 'AA', 'BB', etc.

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is the phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is heredity?

Back

Heredity is the passing of traits from parents to offspring through genes.

Front

What is the probability of a child being homozygous recessive if both parents are heterozygous (Bb)?

Back

The probability is 25%.

Front

What is the probability of a child being homozygous dominant if both parents are heterozygous (Bb)?

Back

The probability is 25%.

Front

What is the expected percentage of homozygous recessive offspring from a monohybrid cross?

Back

The expected percentage is 25%.

Front

What is a dihybrid cross?

Back

A dihybrid cross is a genetic cross that examines the inheritance of two different traits.
