FLASHCARD QUESTION

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses (e.g., Rr, nn).

2.

FLASHCARD QUESTION

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype (e.g., having freckles, being green).

3.

FLASHCARD QUESTION

Front

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 (e.g., G in Gg).

4.

FLASHCARD QUESTION

Front

What does it mean if an allele is recessive?

Back

A recessive allele is one that only expresses its trait when two copies are present in the genotype (e.g., g in gg).

5.

FLASHCARD QUESTION

Front

What is a hybrid organism?

Back

A hybrid organism has two different alleles for a trait (e.g., Cc, where C is dominant and c is recessive).

6.

What is a homozygous organism?

Back

A homozygous organism has two identical alleles for a trait (e.g., MM or mm).
