Graphic representation of family inheritance.. Pedigree of Queen Victoria. Inheritance patterns:. Autosomal. dominant:. Examples: Polydactyly. The Mayan Way. The Mayans hunted many different types of animals using bows and arrows. They used these animals to feed their families.. turkey. agouti. deer. bass fish. peccary. Hunters would have to kill enough animals to feed their families. The more people in their family, the more animals they needed to hunt.. What are the Dominant and Recessive Traits in Humans?. There are over 200 traits that are transmitted from generation to generation in humans. These interesting aspects of human genetics are known as hereditary traits. 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. Humans have 23 pairs of chromosomes, containing 3 billion letters of DNA code and 24,000 genes.. One set comes from MOM and one set comes from DAD. There are 22 pairs of autosomes and 1 pair of sex chromosomes, X and Y.. X-LINKED DOMINANT INHERITANCE. X-LINKED INHERITANCE. dr. . Retno. . Sutomo. , Ph.D., . Sp.A. .. X-LINKED RECESSIVE INHERITANCE. Segregation of X-linked recessive allele. Carrier mother. Segregation of X-linked recessive allele. Gene regulation Genetically related genotypes with striking phenotypic differences, but similar allelic architecture. Within a genotype – striking phenotypic differences between growth stages and/or between tissues. Patterns of inheritance. Homework - Multiple Alleles: Hierarchy. Sometimes there are more than 3 alleles, occurring in a dominance hierarchy. Coat Colour in Rabbits.
