  1. 2. a ratio that states the number of times an outcome is likely to occur out of a possible 100 times
  2. 5. the basic unit of heredity that consists of a segment of DNA on a chromosome
  3. 6. an alternate form of a gene for a specific trait or gene product
  4. 7. a chart used to show all the ways genes from two parents can combine and be passed to offspring; used to predict all genotypes that are possible
  5. 10. a sperm or egg cell, containing half the usual numnber of chromosomes of an organism, which is found only in the reproductive organs of a plant or animal
  6. 12. a comparison between two quantities, often written with a colon
  7. 13. the passing of genes from parents to offspring; the genes are expressed in the traits of the offspring
  8. 15. a term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype
  9. 16. the likelihood or that a specific outcome will occur out of a total number of outcomes
  10. 17. a female reproductive cell
Down
  1. 1. a term that describes an allele that is not expressed when combined with a dominant form of the gene
  2. 3. the genetic makeup of an organism; including its genes; the genetic material of an organsim
  3. 4. a type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells
  4. 8. part of the process of sexual reproduction in which a male reproductive cell and a female reproductive cell combine to make a new cell that can develop into a new organism.
  5. 9. a part of sexual reproduction in which cells divide to form sperm cells in a male and egg cells in a female
  6. 11. a male reproductive cell
  7. 14. the observable characteristics or traits of an organism
