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.

What is a dominant gene?

Back

A dominant gene is one that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive gene?

Back

A recessive gene is one that only expresses its trait when two copies are present in the genotype.

Front

What is a genotype?

Back

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

Front

What is a phenotype?

Back

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

Front

What is 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 incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a third phenotype that is a blend of the two.

Front

What is a gene?

Back

A gene is a segment of DNA that codes for a specific protein, which leads to a particular trait.

Front

What is an allele?

Back

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

What is the P generation in Mendelian genetics?

Back

The P generation refers to the parental generation in a genetic cross, which is used to produce the F1 generation.
