Heredity & Genetics

2. I am the chance that something will happen. I am usually expressed as a %, fraction, or decimal.
4. I am one of the 4 nitrogen bases that make up the steps in DNA. I pair with adenine.
6. I am a characteristic in an organism. Offspring get me from their parents.
8. I am the scientific term for "twisted ladder", the shape of DNA.
9. I am one of the 4 nitrogen bases that make up the steps in DNA. I pair with guanine.
13. I am a term used when an organism has only one type of allele for a trait/gene. I am commonly used to describe dogs when there is only 1 breed (example: 100% German Shepherd).
15. I am a type of allele that, if even just one of me is donated from a parent, I will show up in the offspring. I am "stronger".
17. I am a set of boxes used to help predict the probability that a trait will be passed on to the offspring.
18. I am a "choice" within a gene/category. Two common forms of me are dominant & recessive.
20. I am one of the sections/stripes on a chromosome. I am considered to be a "category" for an organism. Humans have approximately 20,000-22,000 of me.

1. I carry genes to the offspring inside reproductive cells. Humans have 46 of me (23 from mom, 23 from dad).
3. I am a type of allele that only shows up in the offspring if the dominant is not present (or, there are two of me).
5. I am two or more traits that show up in one thing. An example of me is a vehicle that can use both electricity and gas for power.
7. I am one of the 4 nitrogen bases that make up the steps in DNA. I pair with thymine.
10. I am what genes are coded to create. You would also find me in meat.
11. I am the tiny molecule that makes up proteins.
12. I am the male reproductive cell.
14. I am the molecule that acts as an organism's instruction book, or blueprint. A copy of me is found in nearly every cell in your body. If stretched out, I would be approximately 6 feet long.
16. I am one of the 4 nitrogen bases that make up the steps in DNA. I pair with cytosine.
19. I am the female reproductive cell.
