What is the definition of an allele?
An allele is a variety of a gene.
An allele is the genetic makeup of an organism
An allele is another word for a gene.
- 5. Multiple ChoiceAn allele whose trait only shows up when no dominant allele is present.hidden alleledominant allelerecessive allelepresent allele
- 6. Multiple ChoiceWhat is the definition of Homozygous?When one allele is dominant and one is recessiveWhen an individual has two sets of the same allele.when it is neither dominant or recessive
- 7. Multiple Choice
A gene is...
A heritable factor that controls a specific characteristic
An allele
A length of DNA which occupies a specific position on the chromosome
- 8. Multiple Choice
What does the law of segregation state?
Separate genes are passed independently from each other, from parent to offspring.
Every individual possesses two alleles for any particular trait and which allele a parent gives its offspring is completely random.
Just because an allele is dominant, doesn't mean it is inherited more often.
A recessive allele is expressed less than a dominant allele.

What does the law of independent assortment state?
Punnet squares are able to predict the phenotypes and genotypes of offspring.
Offspring inherit one allele from each parent.
Separate genes are passed independently from each other from parent to offspring.
- 10. Multiple Choice
What is the law of dominance?
One of the pairs of inherited traits will be dominant and the others recessive unless both the factors are recessive.
There will always be a dominant allele.
One of the pairs of inherited traits will be dominant and the others recessive.

When one allele is dominant and one allele is recessive.
When both alleles are dominant.
- 12. Multiple Choice
What is the definition of heterozygous?
When both alleles are dominant
When one allele is dominant and one is recessive.
When both alleles are recessive.
When one gene is dominant and one is recessive.
