Patterns of Heredity

2. a ratio that states the number of times an outcome is likely to occur out of a possible 100 times
5. the basic unit of heredity that consists of a segment of DNA on a chromosome
6. an alternate form of a gene for a specific trait or gene product
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
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
12. a comparison between two quantities, often written with a colon
13. the passing of genes from parents to offspring; the genes are expressed in the traits of the offspring
15. a term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype
16. the likelihood or that a specific outcome will occur out of a total number of outcomes
17. a female reproductive cell

1. a term that describes an allele that is not expressed when combined with a dominant form of the gene
3. the genetic makeup of an organism; including its genes; the genetic material of an organsim
4. a type of reproduction in which male and female reproductive cells combine to form offspring with genetic material from both cells
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.
9. a part of sexual reproduction in which cells divide to form sperm cells in a male and egg cells in a female
11. a male reproductive cell
14. the observable characteristics or traits of an organism
