Consider a heritable autosomal disease with an incidence in the population of 1 per thousand. On average, individuals with the disease have 80% as many children as the population average. In answering the various parts of this question, assume that mating is random. Now assume that the mutation rate is zero, that the disease is recessive, and that the disease allele is maintained in the population by heterozygote advantage. Calculate the heterozygote advantage,

a.some invertebrates to withstand temperatures as low as –18°C without freezing, in presence of glycoproteins

b.Sodium, potassium, or chloride ions involve to increasing  the blood freezing point, so the lack of these ions some species help to lower the blood freezing point

c.Amphibians release large amount of glucose into the blood to prevent freezing of blood in cold

d.Sodium, potassium or urea function as anti freezing in their blood
