Unit 1 Formative

3. Different versions of a gene.
4. A variation type with distinct, separate categories or forms, with no intermediate states.
5. A variation type in which a trait has a range of forms, with gradual differences.
8. physical appearance or observable traits of an organism
9. Having two identical alleles for a particular gene.
13. Characteristics passed from parents to offspring, determined by genes.
14. Is expressed in an organism even when only one allele is inherited; overpowers the other allele.
15. Reproduction that is beneficial in environments where adaptability and genetic diversity are key for survival, but it requires more energy and time.

1. Having two different alleles for a particular gene.
2. A segment of DNA that contains a code for a specific characteristic (trait).
6. Is only expressed when an organism inherits two identical alleles for that trait; is overpowered by the dominant allele.
7. Reproduction that is faster and more energy-efficient, making it ideal for stable environments, but it lacks genetic diversity, which can be a disadvantage in the long run.
9. A cell that has one set of chromosomes.
10. A cell that has two sets of chromosomes, like human somatic cells.
11. he combination of alleles that one organism has for a trait
12. the complete set of an organism's chromosomes, arranged and displayed in pairs based on size, shape, and number
