Unit 7 Vocabulary

4. A tool that geneticists use to map out the inheritance of traits
5. A number that describes how likely it is that an event will happen.
7. A trait that is not inherited in an organism’s DNA, but develops after birth
9. The passing on of physical or behavioral traits from organisms to their offspring
12. A trait that has been passed on to an organism from its parents through genetics
17. Different forms of a gene for the same characteristic
19. A plant, animal, or human born of living organisms
20. When an organism receives two different alleles for a given gene
22. An organism that has two of the same alleles for a trait
23. The genetic makeup an individual organism

1. The physical appearance and outward traits of an organism that is the result of its genetic makeup
2. A diagram that represents the probability of all possible genetic outcomes for the offspring of two parents based on the parents’ genetic makeup
3. The study of how traits are inherited, or passed on from organisms to their offspring.
6. Scientists who study patterns of inheritance using letters to represent alleles
8. One unit of DNA that holds genetic information and tells cells what traits to express
10. this carries all genetic information about a living thing
11. father of modern genetics
13. When an organism receives two same alleles for a given gene
14. A gene that overpowers a recessive gene, this type of gene is expressed in the offspring; represented with a capital letter
15. An inherited characteristic
16. A thread-like structure inside the nucleus of a cell that contains genes
18. An organism that has one dominant allele and one recessive allele
21. a gene that can be hidden (or masked) by a dominant gene, it is not expressed in the offspring unless it is paired with an identical allele
