What is an inheritable genetic trait?

Back

An inheritable genetic trait is a characteristic that can be passed from parents to offspring through genes, such as eye color.

What does it mean if an allele is dominant?

Back

A dominant allele is one that expresses its trait even when only one copy is present in the genotype, such as Y for yellow body.

Who is known as the 'father' of modern genetics?

Back

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

What is the genotype of an organism?

Back

The genotype is the exact genetic makeup of an organism, represented by letters (e.g., RR, Tt, PP).

Front

What is the phenotype of an organism?

Back

The phenotype is the observable physical characteristics of an organism, such as height or color.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the physical expression of those genes.

Front

What are alleles?

Back

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

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a trait, such as YY or yy.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a trait, such as Yy.

Front

What is a trait?

Back

A trait is a specific characteristic of an organism, which can be influenced by genetics and the environment.
