PPT-MULTIPLE ALLELES Definition

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. In fact we already did this when we were discussing the ABO blood group polymorphism Just to get some notation out of the way though lets de64257ne ij as the frequency of genotype and as the frequency of allele Then ij if if Unfortunately the simpl 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. Punnett. Squares and to discuss independent assortment and different types of dominances. . 11.3. Independent assortment. Do alleles get passed together to the next generation?. 2 Factor Cross. (RRYY x . Other Patterns of Inheritance. Not all genes show a simple pattern of inheritance…. Many genes have more than two alleles. Many traits are controlled by more than one gene. Complete Dominance. Definition: . Gene and Genotypic frequencies. The Hardy Weinberg law states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.. 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). Purpose. : Allows you to communicate precisely what you want to say.. A writer uses definition to:. Let the reader know what you mean when you use unfamiliar words (ex: accoutrement), words that are open to interpretation (ex: freedom), or familiar words that are used in a particular sense. . Stack before free surface multiple removal. Multiple attenuation. Free surface multiple attenuation. Stack after free surface multiple removal. Multiple attenuation. Internal multiple attenuation results . 7/22/2009 t housands of different g enes and g typically have two copies of every The two copies (or alleles) of the gene may or may not be identical, and one may be dominant in determining the phen LinkageLinkage can be physical or statistical wefocus on physical - easier to understandBecause of recombination Mendel developslaw of independent assortmentBut loci do not always assort independently Exceptions.

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.
