A sequence of bases on a DNA molecule that codes for a protein (polypeptide) results in characteristics (4) 4. Genetic constitution of an organism - the different alleles on an organism (8) 5. The allele that is expressed in preference (usually capital letter) (8) 8. One or more versions of the same gene (7) 10. The expression of the genetic constitution and its interaction with the environment (9) Down 2. Individuals with characteristics toward the middle range are more likely to survive and reproduce. This occurs when environment isn't changing and reduces the range of possible phenotypes (11, 9) 3. Both alleles expressed equally in the phenotype and neither one is recessive (2, 8) 6. Allele which is only expressed if homozygous (9) 7. A group of similar organisms that can reproduce fertile offspring (7) 9. Refers to cells in which the nucleus only contains single copy of the chromosomes e.g. gametes (7, 1)
