1. Show a cross (drawing the Punnett square) between a female who is a carrier for Hutchinson's disease (a recessive trait) and a male who does not have
Hutchinson's disease. Remember that Xh is the recessive allele for Hutchinson's
disease and that X is the dominant allele for non-Hutchinson's phenotype. The
Y chromosome that only males have, will not have the Hutchinson's allele (Y
only). You can use your notes if needed
a. What is the probability that the above parents will have a son that has
Hutchinson's disease?
b. What is the probability that the above parents will have a daughter that
has Hutchinson's disease

Which of these is true of the cytoplasm of an unfertilized egg? a. it is an unevenly distributed mixture of mrna, proteins, organelles, and other substances. b. it does not contain substances that are important in directing development. c. these substances are supplied by the sperm. d. it does not contain substances that are important in directing development. e. development is directed solely by the surrounding cells. f. it is a homogeneous mixture of mrna, proteins, organelles, and other substances. g. it does not contain substances that are important in directing development. h. these substances are produced by the dna of the fertilized zygote.
