Suppose that a dominant allele (p) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. if two heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring?
a. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (75 percent pp; 25 percent pp)
b. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent pp; 50 percent pp; 25 percent pp)
c. 50 percent chance of a polka-dot tail and 50 percent chance of a solid colored tail (50 percent pp; 50 percent pp)
d. 25 percent chance of a polka-dot tail and 75 percent chance of a solid colored tail (25 percent pp; 50 percent pp; 25 percent pp)

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
