the allele for dimples (d) is dominant to the allele for no dimples (d). a man heterozygous for
dimples marries a woman who is also heterozygous for dimples.
a.) what is the man's genotype and the woman's genotype?
b.) what is the man's phenotype and the woman's phenotype?
c.) do a cross to determine all potential dimple genotypes and phenotypes for the offspring of this
man and woman.

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
