The student then covered the dishes and very carefully placed them in different temperatures. She ten them for two
hours then she measured how far the red colour had dithised into the agar around each hole
The table shows the students results.

a Complete the table by calculating the mean distances diffused by the red colour in each dish (Give each distance

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
