Question

there is a 1/2 · 1/2 = 1/4 chance of getting two heads in a row. question: when traits are inherited, what is the probability of each offsprings genotype? 1. model: to determine the probability of a trait combination such as black fur and red eyes, consider each trait separately. fill in the punnett square for each trait. then determine the probability of black fur and the probability of red eyes. express each probability as a fraction. parent 1 fur genotype: ff parent 2 fur genotype: ee parent 2 fur genotype: ff probability of black fur 3/4 probability of red eyes 1/2 parent 1 fur genotype: ee 2. predict: now multiply the probabilities together to find the probability of black fur and red eyes. express

Explanation:

Step1: Identify given probabilities

The probability of black fur is $\frac{3}{4}$ and the probability of red eyes is $\frac{1}{2}$.

Step2: Use multiplication rule for independent - events

Since the inheritance of fur color and eye - color are assumed to be independent events, we multiply the probabilities. $\frac{3}{4}\times\frac{1}{2}=\frac{3\times1}{4\times2}=\frac{3}{8}$.

Answer:

$\frac{3}{8}$
