ABO blood groups - 3 different alleles (IA, IB, i) - 4 phenotypes (A, B, AB,O) - 6 Genotypes: Type A- IAIA or IAi Multiple Alleles - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. This is a full lesson. Genetics PowerPoint #2. ... states that alleles (genes) that you receive from your parents sort . genetics behind multiple alleles BLOOD TYPE The gene for blood type has 3 possible alleles. Many genes have two alternate forms but several other have more than two alternate forms. 2. View Multiple Alleles.pptx from MATH MA 366 at V.I.P Commerce College Talagang, Chakwal.

Environmental Influence, Sex-Linked Traits. - Each Individual can only have 2 alleles for each trait; one from each parent. O = OO In this presentation. Multiple alleles - for some traits there are more than two alleles in the species • Single individual cannot have more then two alleles for each trait (1 on each homologous chromosome) • Multiple alleles explains why there are four different blood types (A, B, AB, and O) Multiple Alleles. Multiple alleles 1. Blood type – A = AA or AO. SB3i for the Edexcel 9-1 GCSE scheme of work. B = BB or BO . Co-Dominance and Blood-typing, Incomplete Dominance, Genetic Disorders and Karyotyping, Pedigrees and Genetic Inheritance. More than two alleles at the same locus give rise to a multiple allelic series. Multiple alleles can + MULTIPLE ALLELE PRESENTED BY: MARIE ELAINE S SEBASTIAN 2. Multiple Alleles, Multiple Genes, and Lethality Multiple Alleles Multiple Genes Lethality A. REVIEW: Incomplete A form of Dominance intermediate inheritance in which one allele for a specific is not + MULTIPLE ALLELE Anallele which consists of three (3) or more alleles of the same gene However, individuals within the population are only able to hold two of them It can only be studied in populations 3. In traits with multiple alleles, each individual can carry any two of the several possible alleles. This resource contains a starter activity which matches the 5 question starter activity on the first slide, but more questions have been added to the 'Who wants to be a millionaire ppt'. GENETICS AB = AB. Multiple Alleles . Multiple Alleles Examples: ABO blood groups in humans Coat color in rabbits Genetic polymorphism vs. genetic monomorphism Major histocompatibility complex (HLA in humans) Story of the cheetah B. Multiple Alleles cont. Ex. You will need the Edexcel worksheets for this lesson. Allele is a shorter term than allelomorph (another form) is the alternate form of gene. 3 or more alleles of the same gene that code for a single trait; In humans, blood type is determined by 3 alleles – A, B, and O; BUT each human can only inherit 2 alleles.
