In a population, there may be more than two alleles for a given trait. If a gene exists in more than two alleles, it is said to have . multiple alleles. Coat colour in rabbits. E.g. Coat colour in rabbit controlled by 3 alleles. What you should know:. The ‘etiquette’ used to represent genetic crosses.. Know what is, and how to represent a monohybrid cross.. Know what is, and how to represent a cross showing sex-linkage.. Natural Selection. Definition. : A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals . because. of those traits. Stresses from the environment creates situations where the organisms with a beneficial trait will survive and reproduce, those without will die off. Multiple Alleles. More than 2 alleles for a gene. Dominance hierarchy (one allele dominates over the other). Ex. Fruit Fly eye colour . 4 alleles: Red, Apricot, Honey, White. To show dominance hierarchy use first letter of the gene name (E=Eye colour) and a superscript to reflect how dominant it is (1 is most dominant). and. DNA & RNA. What is . Genetics. ?.

Genes which have more than two alleles.. Have . 3. or more alleles for the same gene (or at a single locus). . In Other Words – there are 3 or more alleles that create the different traits. . At most one individual will have 2 alleles or 1 pair  (unit factors exist in pairs).. Review 8. Important Vocabulary. Gene – piece of a chromosome that codes for a trait. Trait – a specific characteristic that varies from one individual to another. You are your parents!. Dad’s chromosomes.
