Back

mutations

Front

What is the genetic code for the gene? (Options: phenotype, genotype, homozygous)

Back

genotype

Front

Define genotype.

Back

The genetic makeup of an individual, consisting of alleles inherited from parents.

Front

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to variations in traits.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even if only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is homozygous?

Back

Having two identical alleles for a particular gene.
