One type of roan color in horses is fully dominant over normal solid color and results in the presence of white hairs interspersed among the solid color hairs. the locus for one type of paint in horses (overo paint) is fully dominant, but when homozygous the overo allele is lethal. both loci are autosomal. two roan and paint horses that are heterozygous for roan and heterozygous for overo paint were crossed. what is the probability that their first offspring is also a roan and paint horse? consider only living progeny.

1/2= 0.5

Step-by-step explanation:

Combination of chromosomes x and y give four possible outcomes as progenies. these out comes are xx, xy, yx, yy. ( considering only living progeny)

For heterozygous offspring only two outcomes possible that is xy and yx .

Therefore the probability that their first offspring is also a roan and paint horse can be given as  = 1/2

step-by-step explanation:

their are no angles. sorry cant .

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
