Genetics

5. a specific characteristic of an organism
7. this law states the two alleles for a heritable character separate during gamete formation and end up in different gametes
8. an allele that will not how unless both of the individuals copies of that gene have this genotype
9. a gene at one locus alters the phenotypic expression of a gene at a second locus
12. Gregor Mendel created this many concepts of inheritance
15. true breeding parents
17. alternate versions of a gene
18. tool used to cross genotypes of two individuals
20. genetic makeup of an organism
21. both traits are shown
22. an additive effect of two or more genes on a single phenotype

1. organism with two identical alleles
2. the organism that Gregor Mendel experimented on
3. disease that the heterozygotes are resistant to malaria
4. family tree that describes the interrelationships of parents and children across generations
6. an individual that is heterozygote for a trait and can pass it on
10. dominance when traits are blended
11. the recessive blood type
13. organism that has two different alleles for a gene
14. a variation of a gene that will produce a certain phenotype, even in the presence of other alleles
16. one gene with multiple phenotypic effects
19. physical characteristics of an organism
