What is Mendelian Genetics?

Back

Mendelian Genetics is the study of how traits are inherited through the interactions of alleles, based on the principles established by Gregor Mendel.

What does the term 'allele' mean?

Back

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

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles only express their traits when two copies are present.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the combination of alleles (e.g., TT, Tt, tt).

Front

What is a phenotype?

Back

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

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., TT or tt).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Tt).

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

What do the letters on the top and side of a Punnett square represent?

Back

The letters represent the possible alleles contributed by each parent.

Front

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.
