PPT-Multiple Alleles

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 EEye colour and a superscript to reflect how dominant it is 1 is most dominant. 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 Exceptions. 1.31.13.

Chapter 10 Section 1. Mendel’s Experiment. In the mid 19. th. century, a monk named Mendel studied how traits are passed from one generation to another.. Experimented on . garden peas. .. .  green pea plants reproduce sexually (produce gametes). Karyotypes. To find what makes us uniquely human, we have to explore the human genome. . A . genome. is the full set of genetic information that an organism carries in its DNA.. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells. . 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.. Exceptions.

Dr. Howard Gardner, professor of education at Harvard University.. It suggests that the traditional notion of intelligence, based on I.Q. . testing, is far too limited. Instead, Dr. Gardner proposes eight . 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 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. Homothallism.  refers to the possession, within a single organism, of the resources to reproduce sexually i.e., having male and female reproductive structures on the same . thallus. .. . The opposite sexual functions are performed by different cells of a single mycelium..
