A karyotype is a map of an individual’s chromosomes (DNA). The image below shows a normal human karyotype (A) and the karyotype of the DNA from Henrietta’s cancer cells (B). Use what you have learned about DNA, Central Dogma, the cell cycle, and cancer to explain what may have caused Henrietta’s cancer.

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
