Mendelian and Non-mendelian Inheritance Lesson

Front

What is incomplete dominance?

Back

A type of inheritance pattern where the phenotype of a heterozygote is an intermediate of the two homozygous phenotypes, resulting in a mixture of traits.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

Front

How are dominant alleles represented?

Back

Dominant alleles are represented by a capital letter.

Front

Who is known as the Father of Genetics?

Back

Gregor Mendel, who conducted experiments on pea plants to understand inheritance.

Front

What does the genotype 'Tt' represent?

Back

A heterozygous genotype where 'T' is the dominant allele for tallness and 't' is the recessive allele for shortness.

Front

What is co-dominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical expression of that genetic makeup.

Front

What does a Punnett square illustrate?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What is the significance of Gregor Mendel's work?

Back

Mendel's work established the basic principles of heredity, including the laws of segregation and independent assortment.

Front

What is a recessive allele?

Back

An allele that is masked by the presence of a dominant allele and only expressed in a homozygous condition.
