Across
- 3. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
- 7. a cell or organism having a single set of chromosome
- 8. organism’s reproductive cell containing one set of chromosomes
- 9. the likelihood of an event to occur
- 11. a cell or organism that has paired chromosomes
- 14. a graphical representation of the possible genotypes of offspring
- 16. characteristics or attributes of an organism that are expressed by genes and/or influenced by the environment
- 18. a version of a gene that will produce a certain appearance/trait
- 19. the action or process of fertilizing an egg
- 20. a version of a gene which will not create the corresponding appearance/trait if a dominant allele is present
Down
- 1. an organism's physical appearance shows a blending of both alleles
- 2. a genetic condition in which an individual inherits different alleles for a particular gene from each parent
- 4. one of two or more alternative forms of a gene and are found at the same place on a chromosome
- 5. new organisms produced by a living thing
- 6. genetic condition in which an individual inherits the same alleles for a particular gene from both parents
- 10. Also known as “monozygotic twins,” this occurs when a single fertilized egg (zygote) splits in two
- 12. an organism’s set of heritable genes that can be passed down from parents to offspring
- 13. Also known as “dizyogtic twins,” occurs when two separate eggs are fertilized by two separate sperm cells
- 15. an organism's physical appearance is an expression of BOTH alleles simultaneously
- 17. also known as a somatic cells; any cell other than a reproductive cell
