Basic Genetics Flashcard

Front

What is a genotype?

Back

The actual alleles you inherit from your parents for a particular trait.

Front

What is a phenotype?

Back

The physical expression or characteristics of a trait.

Front

What does homozygous mean?

Back

Having two identical alleles for a particular gene (e.g., BB or bb).

Front

What does heterozygous mean?

Back

Having two different alleles for a particular gene (e.g., Bb).

Front

What is a dominant allele?

Back

An allele that covers up or masks another form of that trait.

Front

What is a recessive allele?

Back

An allele that is masked by a dominant allele and only expressed when homozygous.

Front

What is an allele?

Back

A variant form of a gene that can produce different traits.

Front

What is the purpose of studying genetics?

Back

To understand how traits are passed from parents to offspring.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.

Front

What does it mean if an organism is homozygous recessive?

Back

It has two recessive alleles for a trait (e.g., gg).
