A)
Consider that a plant with genotype RR has red flowers and a plant with genotype WW has white flowers. This plant species expresses
incomplete dominance for flower color when the plant is heterozygous.
The offspring of a cross between an RR plant and a WW plant would be

A) A genetic disease is found in a family that affects the immune system, lungs, heart, and kidneys. A DNA analysis of several affected and
unaffected family members determines that the disease is caused by a mutation in a single gene. What type of inheritance pattern is shown in this
disease? (1 point)
incomplete dominance
polygenic trait
codominance
pleiotropy
