2. All chromosomes with the exception of the sex chromosomes.
3. The genetic make-up of an organism.
4. Masks the recessive allele in a heterozygous individual.
8. Occurs when neither allele is dominant. They both have an affect on the
heterozygous individual which shows a phenotype between the two
homozygous phenotypes.
9. A model used to show the probabilities of the results of a genetic cross.
12. Section of chromosome (DNA) that codes for a specific trait.

13. a threadlike structure of
nucleic acids and protein found
in the nucleus of most living cells,
carrying genetic information in
the form of genes.
16. Genotype of an individual
with two of the same alleles for a given trait.
17. Any one of two or more alternative forms of a
gene that may occur alternatively at a given site on a
chromosome. Alleles may occur in pairs, or there
may be multiple alleles affecting the expression of a
particular trait. If paired alleles are the same, the
organism is said to be homozygous for that trait; if
they are different, the organism is heterozygous.
18. The pair of chromosomes that determine the
gender of an individual.
Heterozygous
Homozygous

1. If two alleles in a gene pair are different, then one allele can control the expression of the trait and the other can be
hidden.
5. deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of
chromosomes. It is the carrier of genetic information.
6. A diagram of the genetic history of an individual: can show how a trait is inherited over several generations of a
family. (a genetic family tree)
7. Genotype of an individual with two different alleles for a given trait.
9. The external appearance of an individual determined by it’s genotype.
10. Any characteristic that can be passed be inherited from parent to offspring.
11. The complete genetic material contained in an individual.
13. An individual who has the allele for a trait or disease but does not have the disease or outwardly express the trait.
14. Reproductive cell.
15. Allele that is masked by the dominant allele in a heterozygous individual
