Genetics Review

3. process in sexual reproduction in which male and female reproductive cells join to form a new cell
4. a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
6. reproduction a reproductive process that involves only one parent and produces offspring that are identical to the parent.
8. a genotyope that has two different alleles for a trait
10. an organism's genetic makeup or allele combination
11. a complex molecule containing the genetic information that makes up the chromosomes.
12. a form of asexual reproduction in which a part of the parent organism pinches off and forms a new organism
13. a number that describes how likely it is that an event will occur often expressed as a percentage
15. threadlike structures made of DNA molecules
19. the passing of traits from parents to offspring
20. single-celled reproductive bodies highly resistant to cold and heat damage
21. series of events that cells go through as they grow and divide
22. a genotype that has two identical alleles for a trait
23. a chart that shows all the possible combinations of alleles that can result from a genetic cross

1. different forms of a physical characteristic
2. describes a trait that covers over or dominates another form of that trait.
5. a reproductive process that involves two parents that combine their genetic material to produce a new organism which differs from both parents
7. product of reproduction a new organism produced by one or more parents
9. trait of an organism that can be masked by the dominant form of a trait
14. how a trait appears based on the inherited combination of alleles
16. different forms of a gene that codes for a trait
17. segment of DNA on a chromosome that codes for a specific trait
18. a form of asexual reproduction in which offspring grow from a part of a parent plant
