3. A population of sheep is in Hardy-We inberg equ ilib riu m. The alle le for white wool (W ) has an allele frequency of 0.1 9. and the alle le for b lack wool (w)has an alle le fre quency of 0.81 Whatis the percentage of heterozygous in dividuals in the population?

4. The recessive alle le b occurs with a frequency of 0.8 in a popu la tion of crabs th at is in Hardy-We inbe rg equilib riu m. Whatis the frequency of hom ozygous dominantin dividuals?

2. Use the following information to calculate a prediction of the EBV, EPD of two beef sires with records of progeny. Heritability for yearling weight = 45 a. Sire 1 has 105 progeny that average 1,150 at a year of age with a population average of 1,000 lbs. EBV = EPD = Future progeny record b. Sire 2 has 50 progeny that average 1,200 at a year of age with a population average of 1,100 lbs. EBV = EPD= Accuracy Accuracy Future progeny record- Accuracy Accuracy

woll 4. You have been studying a trait that seems to be present in every generation within 02a particular family. Further, you have observed that every affected offspring has at won least affected parent in any particular generation. bas berswo woll Yang morto vas of oftiziqe om sno vas al Solowoh sdi lozinoo tensy vnam This trait is more likely due to a dominant or recessive allele? a) b) Interestingly, this allele is completely penetrant in the homozygous state while only 75% penetrant in the heterozygous condition. If two heterozygous individuals who carry this allele are mated, what is the expected proportion of affected progeny?
