Mendelian Genetics

Front

What is a heterozygote?

Back

An organism that has two different alleles for a specific trait, such as Rr.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What does homozygous mean?

Back

An organism that has two identical alleles for a specific trait, such as RR or rr.

Front

What is a trait?

Back

An observable characteristic or feature of an organism, such as eye color or height.

Front

Who is known as the father of modern genetics?

Back

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

Front

What is a dominant allele?

Back

An allele that expresses its trait even when only one copy is present (e.g., R in Rr).

Front

What is a recessive allele?

Back

An allele that only expresses its trait when two copies are present (e.g., rr).

Front

What is the principle of segregation?

Back

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

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by the alleles it possesses (e.g., Rr, RR, rr).

Front

What is a phenotype?

Back

The physical expression or characteristics of a genotype, such as having brown eyes.
