Document Summary
Review: pseudohypertrophic muscular dystrophy is a human disorder that causes gradual deterioration of the muscles. Only boys are affected, and they are always born to phenotypically normal parents. Due to the severity of the disease, the boys die in their teens. Is its inheritance sex-linked or autosomal: dominant, sex-linked, recessive, autosomal, recessive, sex-linked, incomplete dominant, sex-linked, dominant, autosomal, currently the only predators of gal pagos marine iguanas are gal pagos hawks. Iguana body size is not correlated with risk of hawk predation, although small iguanas can run faster than large iguanas. A scientist studying these beetles knows that their eggs hatch in early spring, the larvae grow through the late spring and summer, then metamorphose into adults in late summer. Beetles mate and females lay eggs in the early fall, and adults die in the early winter. Recently some beetles with brown wings have been observed in this population.
