It is likely that there are three gene pairs in this cross. there are seven categories of phenotypes. the genotypes of the parents would be combinations of alleles that would produce a 6 cm (aabbcc) tail and a 30 cm (aabbcc) tail, whereas the 18 cm offspring would have a genotype of aabbcc.
if the 18 - cm f1 pig with genotype aabbcc is mated with one of the 6 - cm f2 pigs, what phenotypic ratio would be predicted if many offspring resulted?

Researchers randomly divide participants into groups. each group takes a different amount of omega-3 fatty acid supplements daily for a month. one group receives a placebo. the researchers measure the impact on cholesterol levels in the blood. what is the purpose of random assignment in this experiment? a, to produce treatment groups with similar characteristics b, to ensure that all people with high cholesterol have an equal chance of being selected for the study c, to increase the accuracy of the research results and prevent skewness in the data
