genetics, inheritance, sex-linked recessive, genetics, sex-linked recessive, x-linked recessive, sex-linked diseases, inherited, the "sex chromosomes", the x, y chromosomes, autosomally inherited diseases, inherited, the non-sex chromosomes, autosomes, pairs 1, 22, dominant inheritance occurs, an abnormal gene, one parent is capable of causing disease though the matching gene, other parent is normal, abnormal gene dominates the outcome, the gene pair, recessive inheritance occurs, matching genes must be abnormal to produce disease, one gene, in the pair is abnormal, disease is not manifest, mildly manifest, genetic predisposition to disease, passed on, children, term "sex-linked recessive", referring, specific case of x-linked recessive, related terms, topics, gene, chromosome, inheritance, heredity, disease, genetic counseling, prenatal diagnosis, sex-linked dominant, autosomal dominant, autosomal recessive x-linked diseases, males, males have only one x chromosome, a single recessive gene on that x chromosome, cause the disease, the y chromosome, half, the xy gene pair, in the male, y chromosome doesn't contain most, the genes, the x chromosome, doesn't protect the male, seen in diseases hemophilia, duchenne muscular dystrophy, typical scenarios, given birth, mother, carrier, one abnormal x, father is normal, 25% chance of a normal boy, 25% chance of a boy, 25% chance of a normal girl, 25% chance of a carrier girl, father is has the disease, mother is normal, 50% chance of a normal boy, 50% chance of a carrier girl, x-linked recessive disorders in females, females, get an x-linked recessive disorder, it would be very rare, an abnormal gene on the x chromosome from each parent would be required, a female has 2 x chromosomes, could occur, in the two scenarios below, given birth, mother, carrier, father has the disease, 25% chance of a healthy boy, 25% chance of a boy, 25% chance of a carrier female, 25% chance of a girl, mother has the disease, father has the disease, 100% chance, the child having the disease, whether boy, girl, odds of either of these two scenarios, low that x-linked recessive diseases, "male only" diseases, this is not technically correct.
