Mendelian & Non-Mendelian Genetics

Front

What is Mendelian Genetics?

Back

Mendelian Genetics is the study of how traits are inherited through generations, based on the principles established by Gregor Mendel, which include concepts like dominant and recessive alleles.

Front

What is Non-Mendelian Genetics?

Back

Non-Mendelian Genetics refers to patterns of inheritance that do not follow Mendel's laws, including incomplete dominance, codominance, and polygenic inheritance.

Front

Define Incomplete Dominance.

Back

Incomplete Dominance is a form of inheritance where the phenotype of heterozygotes is intermediate between the phenotypes of the two homozygotes.

Front

Define Codominance.

Back

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

Front

What is a Genotype?

Back

A Genotype is the genetic constitution of an individual, specifically the alleles present for a particular gene.

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

What is Heredity?

Back

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

Front

What is an Allele?

Back

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

Front

What is Homozygous?

Back

Homozygous refers to having two identical alleles for a particular gene, either dominant (AA) or recessive (aa).

Front

What is Heterozygous?

Back

Heterozygous refers to having two different alleles for a particular gene (Aa).
