Phenotypes can even be the molecules produced by genes (e. g. , hemoglobin). population. In the simplest case, each phenotype results from a different allele or combination of alleles of a single gene. In more complex cases, the phenotypes result from complex interactions between many different genes and the environment. Allele: one of several alternative forms of the dna sequence of the same locus. Meiosis: a form of cell division that occurs only in eukaryotes, in which the number of chromosomes is. Genetic recombination: the exchange of genetic material between paired chromosomes during. Although a genotype includes all the alleles of all the. Phenotype: an observable, measurable characteristic of an organism. Genetic polymorphism: the simultaneous occurrence of two or more discrete phenotypes within a.
