Mendel and Punnett Squares

Front

What is a recessive trait?

Back

A trait that can be masked by a dominant trait and is only expressed when two recessive alleles are present.

Front

What is a mutation?

Back

Any change in the DNA sequence that can lead to changes in traits.

Front

Order the following from largest to smallest: cell, nucleus, chromosome, DNA, nucleotide.

Back

cell, nucleus, chromosome, DNA, nucleotide.

Front

Is the dominant trait represented by a lowercase letter?

Back

False, the dominant trait is represented by an uppercase letter.

Front

What is deoxyribose?

Back

A five-carbon sugar found in DNA.

Front

What is a dominant trait?

Back

A trait that is expressed when at least one dominant allele is present.

Front

What is the purpose of a Punnett square?

Back

To predict the possible genetic outcomes of a cross between two organisms.

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

Having two identical alleles for a particular gene.

Front

What does heterozygous mean?
