Why is it important for a scientist to think about their sample size if they are going to extrapolate their data? (Hint: Think about predicting the rainfall this coming March based on only last year, as compared to predicting it based on the past 30 years.) How might a scientist determine if they have enough samples?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4

What is the key to the recognition of codominance?
