The genetic underpinnings of a disease have recently been identified. This disease has been found to result from a single point mutation in the coding sequence of a gene. The normal coding sequence of this gene is 5' - GATTACG - 3'. Which of the following could be the disease-causing form of the gene?

Your neighbor has a flower garden in which there are red flowers and white flowers. These flowers are diploid organisms, and flower color is an autosomal trait. The gene for red flowers (R) is dominant, while the gene for white flowers (r) is recessive.

Which of the following is the genotype of a white flower?

What is the phenotypic ratio for a cross between a plant with blue flowers BB and a plant with white flowers bb?

Your neighbor has a flower garden in which there are red flowers and white flowers. These flowers are diploid organisms, and flower color is an autosomal trait. The gene for red flowers (R) is dominant, while the gene for white flowers (r) is recessive.

Which of the following is the genotype of a white flower?

Each person can have one of four possible blood types: A, B, AB, or O. Blood type A means that the "A" antigen is present on the red blood cell surface. Blood type B means that the "B" antigen is present on red blood cells' surfaces. Blood type "AB" means that both the "A" antigen and the "B" antigen are present on the red blood cells' surfaces. Blood type "O" means that no antigens are present on the red blood cells' surfaces.

Someone with genotype "A/A" or "A/O" will have type A blood. Someone with genotype "B/B" or "B/O" will have type B blood. Someone with genotype "A/B" will have AB blood, and someone with genotype "O/O" will have type O blood.

Assume that blood type is not a sex-linked trait. A mother with genotype "A/O" and a father with genotype "A/B" could NOT have a child with which blood type?

A mother with blood type A and the genotype "A/O" and a father with blood type B and genotype "B/B" have a child with blood type AB. This is an example of what type of inheritance pattern?
