The gene (IGF1) that encodes a growth hormone has one allele (IGF1-A) that is found in small dogs but not in dogs that are very large. What does this suggest about body size of small dogs?
A. Body size depends on how much growth hormone is produced during early fetal development. B. Body size depends on whether or not the IGF1-A allele is present, if it is the dog grows very large, if it is not present the dog retains a small size. C. It suggests that small dogs are small because the IGF1-A allele is expressed, perhaps inhibiting the growth of the dog and the release of growth hormone. D. It suggests that small dogs have more growth hormone released during fetal development but none released after the birthing process. E. Body size depends on nutrition, not on genetics.
You are observing the embryonic development of a new species in your laboratory. This species has indeterminate development. You note a mutation in which one of the blastomeres (early cells) mutates and loses its function. What do you hypothesize would happen to this being?
A. Nothing—the remaining blastomeres would accomodate the formation of the necessary structures of the embryo. B. Immediate embryo death—the remaining blastomeres could not accomodate the formation of the necessary structures of the embryo. C. Uncertain future for the embryo—depending on which blastomere was lost, the remaining blastomeres might accomodate the formation of the necessary structures of the embryo. D. The embryo would certainly lack some features as a result of the lost blastomere.
