Genetics

5. – an organism with 2 identical alleles. (RR, gg, TT, hh)
7. – the different forms of a gene. (tall or short stems, yellow or green seed color)
10. – an organism with 2 DIFFERENT alleles. (Rr, Gg, Tt, Hh)
11. – offspring of many generations that have the same form of a trait
15. – only two possible alleles; one is dominant and one is recessive
17. – a chart that shows all of the possible ways that alleles may combine
18. Assortment - the alleles of two (or more) different genes get sorted into gametes independently of one another

1. – an organism’s physical appearance
2. allele – one whose trait is hidden when a dominant allele is present
3. - When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly
4. – a number that describes how likely it is that an event will occur
6. – an organism’s genetic makeup or alleles
8. – the scientific study of heredity
9. - the passing of physical characteristics from parents to offspring
12. allele – one whose trait always shows up in the organism when it is present
13. – the factors that control a trait.
14. – when a sperm (male) and an egg cell (female) join
16. – a specific characteristic such as stem height or seed color.
