1)adrenal hyperplasia, congenital.
cause:-Congenital adrenal hyperplasia affects a child's normal growth and development. Although it can be life-threatening, most people can lead normal lives with proper treatment.

3)There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
4)Two of the pea lines studied by Mendel bred true for the character of flower color. One line bred true for purple flowers; the other, for white flowers. Any plant in the purple-flowered line—when selfed or when crossed with others from the same line—produced seeds that all grew into plants with purple flowers.
