- 3. Reproduction Production of offspring by a single parent, no union of a sperm cell and an egg cell
- 4. A small section of DNA on a chromosome in humans
- 7. genes Trait that masks or cover over another allele, if the organism has a dominant trait it will show itself
- 8. The physical appearance of a trait in an organism. You can look at someone and see this
- 10. Different forms of a gene. Offspring recieves an allele from the male parent and an allele from the female parent
- 11. genes Trait that is hidden by a dominant allele; only show themselves if the trait is recessive purebred
- 12. The study of how traits are passed from parents to offspring
Down
- 1. Reproduction Involves two different parents who combine their genetic material to produce a new organism
- 2. The passing of traits from the parents to the offspring
- 4. The genes in an organism; for one specific trait we use two letters to represent the genotype
- 5. Controls how offspring will look and how they will function by controlling what proteins each cell will produce. Genetics material found in the nucleus that carries trait
- 6. Contains genes; there are 23 pairs of them are in humans
- 9. A physical characteristic of an organism
