Scientific study of heredity

2. F1 Generation
First filial generation

3. P Generation
Parental generation

4. recessive
Allele that may not be expressed

5. Independent Assortment
Two or more pairs of alleles segregate independently

6. Probability
Likelihood that something will happen

7. Codominance
Both genes in the heterozygous condition are fully expressed—you see both

8. Homozygous
Having identical pair of alleles
TT or tt

9. alleles
Different forms of a gene

10. phenotype
Physical appearance

11. segregation
Law that says two factors for a trait segregate into two different gametes

12. Dominant
Allele that is always expressed if present

13. Monohybrid
Focuses on only one trait using a punnett square

14. Heterozygous
Having two different alleles for the same trait Tt

15. Punnett Square
Grid that shows possible outcomes of a cross

16. Dihybrid Cross
Shows two traits in a punnett square

17. Mutation
Change in a gene

18. Genotype
The alleles that make up an organism

19. Incomplete Dominance
Intermediate forms of traits of two parents are displayed
