What is Non-Mendelian Inheritance?

Back

Non-Mendelian Inheritance refers to patterns of inheritance that do not follow Mendel's laws of segregation and independent assortment. It includes various inheritance patterns such as incomplete dominance, codominance, multiple alleles, and polygenic inheritance.

What is a Genotype?

Back

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

Front

What is a Phenotype?

Back

Phenotype is the observable physical or biochemical characteristics of an organism, determined by both its genotype and environmental influences.

Front

What is Codominance?

Back

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

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What are Multiple Alleles?

Back

Multiple Alleles refer to the presence of more than two alleles for a genetic trait within a population, such as the ABO blood group system.

Front

What is Polygenic Inheritance?

Back

Polygenic Inheritance is a type of inheritance where multiple genes influence a single trait, resulting in a continuous range of phenotypes.

Front

What is a Gene?

Back

A Gene is a segment of DNA that contains the instructions for building a specific protein or set of proteins, which determine traits.

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life, composed of nucleotides that form a double helix.

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in the synthesis of proteins and can also have various functions in gene regulation.
