Name the muscle that compresses the cheeks.

A series of experiments shows that oil content in a diploid corn grain is influenced by five genes (a, b, c, d and e) with additive allelic effect. The highest (X) and the lowest (Y) oil producing corn lines have 20% and 0% oil in the grain, respectively. A plant of unknown genotype has an oil content of 12% from the cross between X and Y lines. What is a possible genotype for this plant? (“+” = additive allele and “-“ = allele is non additive; assume all loci have equal effect).

A scientist has determined the following variances for yield of corn in his fields (8):     Additive genetic variance 30 Dominance genetic variance 50 Environmental variance 20     Assume that there is no genetic-environmental interaction variance. Calculate the narrow-sense heritability indicated by this data.

You tested 20 peanut genotypes in 4 locations in Florida with 3 reps/location. Write EMS (expected mean square) model to estimate variance components associated with genotype, locations, and genotype*location interaction. Estimate broad-sense heritability and genetic gain from the mean square values provided in question.    Source of variation MS Values EMS Model Genotype 7.5     Location 3.4     Genotype* Location 1.2   Error 0.90
