Genetics

3. Genetic makeup in letters.
5. The study of Heredity.
8. Law where pairs of alleles separate during meiosis so that each egg or sperm gets only 1 of each allele.
9. A cross where two traits are observed.
11. To have 2 different alleles, commonly referred to as hybrids.
12. Shows all possible combinations of alleles in a cross.
13. Both alleles are expressed in the heterozygote.
15. Expressed only if homozygous.
16. A genetically determined characteristic.
17. Expressed when in presence of recessive allele.
18. Used to track certain diseases or traits that are passed from generation to generation.
19. Different forms of a gene.

1. To have 2 of the same allele, commonly referred to as purebreds.
2. A cross where one trait is observed.
4. Experimented with traits in garden pea plants to determine basic patterns of inheritance.
6. Neither allele of the pair is dominant, they blend and display a new trait, just like paint.
7. When the trait shows a wide range of varieties.
10. Physical expression of a gene.
14. When gene for trait is on an autosome.
