Genetics Vocab

2. An individual who has one recessive allele for a trait and one dominant allele but does not express the recessive trait (e.g., Aa for a recessive condition).
4. - Having two identical recessive alleles for a trait (e.g., aa).
6. A situation where neither allele is fully dominant, resulting in a blended phenotype (e.g., red + white = pink flowers).
7. Refers to genes located on the X chromosome, which can lead to traits or disorders that are expressed differently in males and females.
9. The genetic makeup of an organism, represented by its alleles (e.g., AA, Aa, aa).
10. A reproductive cell (sperm or egg) that carries half the genetic information of an organism.
12. An allele that masks the expression of another allele in a heterozygous pair (e.g., A in Aa).

1. - Having two identical dominant alleles for a trait (e.g., AA).
3. An allele that is masked by a dominant allele and only expressed when paired with another recessive allele (e.g., a in aa).
5. alleles The presence of more than two allele options for a gene in a population, though an individual inherits only two (e.g., blood type alleles A, B, and O).
8. Having two different alleles for a specific trait (e.g., Aa).
11. The observable traits or characteristics of an organism (e.g., eye color, height).
