Assume that the fasting blood level of a lipid is normally distributed in the population of people who do not have disease "x." there is a smaller distribution curve of the fasting blood levels of this lipid, which also is normal in shape, for the population of persons who have disease "x," and the curve overlaps the upper end (right side) of the curve for people without the disease. draw distribution curves for the diseased and non-diseased populations and discuss the effects upon sensitivity and specificity of setting the cut point for disease and non-disease at various positions on the two overlapping curves

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?

Explain how the number of similarities between the embryos from early stage to late stage is used as evidence of a common ancestry

Which of the following can occur to two segments of a population if they are geographically isolated 1.) they can only share some types of genes 2.)both groups most likely become extinct 3.)they find a way to come back together 4.)eventually they become separate species
