Dominant & Recessive genes (part 1)

Front

What is a recessive trait?

Back

A recessive trait is a trait that is not expressed in the presence of a dominant trait. It only appears when an individual has two copies of the recessive allele.

Front

What is heredity?

Back

Heredity is the passing of traits from parent to offspring.

Front

What is a dominant trait?

Back

A dominant trait is a trait that is expressed or appears in the phenotype even when only one copy of the allele is present.

Front

Who is known as the father of genetics?

Back

Gregor Mendel is known as the father of genetics for his work on inheritance patterns in pea plants.

Front

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

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

Front

What is a genotype?

Back

A genotype is the genetic makeup of an individual, consisting of the alleles inherited from both 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 the principle of segregation?

Back

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