In a population of 10,000 individuals, 300 men are afflicted with a recessive, x-linked disease. 18 woman would be expected to be afflicted in this population
both sickle cell disease and cystic fibrosis. dominant X-linked disease. Gene variations on the X chromosome are the root cause of X-linked diseases. A variation in the one copy of the gene present in each cell is what causes the condition in males (who have only one X chromosome).
Red-green color blindness and hemophilia A: Red-green color blindness are two examples of X-linked diseases. Red-green color blindness is simply the inability to distinguish between the many hues of red and green.
Males who are hemizygous (i.e., have only one X chromosome) will fully express an X-linked disease. Females, who have two X chromosomes, on the other hand, will typically be carriers of the abnormality and are hence typically asymptomatic.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
which class question is this?
answer
Fossil evidence clearly shows that life is old and has changed over time. The study of anatomical features of animals of different species. The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth
Some chemicals can alter the shape of some enzymes, heat also works (think cooking).
