Génétiques: Dominance incomplète & codominance
La dominance incomplète: Une situation ou aucun des allèles qui déterminent un trait sont dominants Lorsque les deux allèles sont présent, un phénotype « nouveau » apparait qui mélange les deux allèles Le phénotype hétérozygote est entre les deux phénotypes homozygotes 2 allèles produisent 3 phénotypes
Incomplete and Codominance
Codominance & Multiple Alleles • Human blood type is an example of both codominance and a trait with multiple alleles • AB = universal acceptor • O = universal donor BLOOD TYPE GENOTYPE CAN RECIVE BLOOD FROM A IAI A, I i A, O B I BI , IBi B, O AB IAIB A, B, AB, O O ii O
Incomplete Dominance and Codominance
Incomplete Dominance and Codominance 1 In Japanese four o'clock plants red (R) color is incompletely dominant over white (r) flowers, and the heterozygous condition (Rr) results in plants with pink flowers For each of the following construct a Punnett square and give phenotypic and genotype ratios of the offspring a) a red plant and a white
Incomplete Dominance, Codominance, and ABO Blood Types
Incomplete Dominance, Codominance, and ABO Blood Types Review of Simple Mendelian Genetics Law of Segregation: each gene has two different alleles that are
Incomplete and Codominance Problems
show incomplete dominance The heterozygous condition results in blue plumage List the genotypic and phenotypic ratios expected from the crosses: a black and blue b blue and blue c blue and white 4 Two short-tailed (Manx) cats are bred together They produce three kittens with long tails, five short tails, and two without any tails
Incomplete Dominance Codominance Multiple Alleles
Incomplete Dominance Codominance Multiple Alleles Polygenic Traits Sex-Linked Traits Incomplete Dominance a third (new) phenotype appears in the heterozygous
Codominance - University of Arizona
Epistasis, incomplete dominance and codominance are all examples of gene interactions that will result in outcomes of dihybrid crosses differing
More Genetics Problems- Incomplete Dominance, CoDominance
More Genetics Problems- Incomplete Dominance, Codominance 1 Snapdragons are flowers that come in both Red (R allele) and White (R’ alllele) dominant colors When the two are crossed they are incompletely dominant which produces a “blended” color pink (RR’ genotype) (a) Show a Punnett square crossing a red snapdragon with a white one
Remember: Co-Dominance, and Sex- Linked Traits
Incomplete Dominance, Co-Dominance, and Sex-Linked Traits It is a little more complicated than Mendel thought Remember: • An allele is: a possible form of a gene • Normally, there are 2 alleles for a given gene (Dominant and Recessive ) • Sometimes though, there are multiple alleles which allow 3,4,5 or more forms of a gene, but
