Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart. In other words, the nearer two genes are on a chromosome, the lower the chance of recombination between … NettetIn X-linked dominant inheritance, the gene responsible for the disease is located on the X-chromosome, and the allele that causes the disease is dominant to the normal allele in females. Because females have twice as many X-chromosomes as males, females tend to be more frequently affected than males in the population. NettetIt refers to the genetic representation that depicts the family tree or biological relationship between individuals of the new generation and their ancestors. A pedigree chart also entails information about genetic disorders in the family history. It helps in studying different patterns of inheritance and genetic traits of different individuals. neighbor comic book
