Punnett Square Practice Flashcard

Front

What is a homozygous recessive genotype?

Back

A genotype consisting of two identical recessive alleles, such as 'dd'.

Front

What are the alleles of the highlighted box in a Punnett square?

Back

The alleles are represented by letters, for example, 'Ff'.

Front

What is a genotype?

Back

An organism's genetic makeup, represented by letters that denote the actual genes.

Front

What is a phenotype?

Back

The observable traits or characteristics of an organism, influenced by its genotype.

Front

What does heterozygous mean?

Back

A genotype consisting of two different alleles, such as 'Aa'.

Front

What does homozygous mean?

Back

A genotype consisting of two identical alleles, either dominant (e.g., 'AA') or recessive (e.g., 'aa').

Front

What is a dominant allele?

Back

An allele that can cover or mask the effect of another allele; represented by an uppercase letter.

Front

What is a recessive allele?

Back

An allele that is masked by a dominant allele; represented by a lowercase letter.

Front

What is a Punnett square used for?

Back

A tool used to predict the genetic outcomes of a cross between two organisms.

Front

What does it mean if an organism is homozygous dominant?

Back

It has two dominant alleles for a trait, such as 'AA'.
