PPT-Dihybrid crosses and autosomal linkage

Patterns of inheritance Homework Multiple Alleles Hierarchy Sometimes there are more than 3 alleles occurring in a dominance hierarchy Coat Colour in Rabbits Agouti coat is dominant to Chinchilla coat which is dominant to Himalayan coat which is dominant to Albino coat. Genotype . vs. Phenotype. Genotype: An organism’s genetic makeup which consists of the alleles that an organism inherits from it’s parents (ex: . Ee. ,. EE, or . ee. ).

Law of Independent Assortment. Autosomal linkage. Genes that do not obey Mendel’s Law of Independent Assortment. Linked genes. Linkage is the tendency for a group of genes, on the same chromosome, to be inherited together. Patterns of inheritance. Homework - Multiple Alleles: Hierarchy. Sometimes there are more than 3 alleles, occurring in a dominance hierarchy. Coat Colour in Rabbits. Agouti coat is dominant to Chinchilla coat, which is dominant to Himalayan coat, which is dominant to Albino coat.  2017. Law of Independent Assortment.
