Genetics

4. The particular alleles of an organism.
5. A genetically determined characteristic.
7. An individual with two alleles that are the same for a particular trait.
8. An allele which is only expressed when two of them are present. Expressed with a lower-case letter. (i.e. ‘b’).
9. Different forms of the same gene.
11. A tool that helps to show all possible allele combinations of gametes in a cross of parents with known genotypes

1. An individual with two alleles that are different for a particular trait.
2. The observable characteristics of an individual resulting from its genotype.
3. An organism that is homozygous for a particular trait.
6. An allele which is always expressed, even if only one is present. Expressed with an upper-case letter (i.e. ‘A’).
10. Chart A diagram that shows the phenotypes of related individuals.
