Front

What is a harmful mutation?

Back

A harmful mutation is a change in the DNA that negatively affects an organism's ability to survive or reproduce, such as a rabbit with short deformed legs.

Front

What is the genotype for a yellow plant if G = green and g = yellow?

Back

Front

What does the term 'genotype' refer to?

Homozygous means having two identical alleles for a particular gene, such as AA or aa.

Front

What does heterozygous mean?

Back

Heterozygous means having two different alleles for a particular gene, such as Aa.

Front

What is a Punnett Square used for?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What allele combination should go in the missing box if the options are AA, Aa, aa?

Back

The correct allele combination is Aa.

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic code (alleles), while phenotype is the physical expression of those genes.

Front

What does it mean if a mutation is beneficial?

Back

A beneficial mutation is a change in the DNA that enhances an organism's ability to survive or reproduce.
