Scenario: Restaurant Meals A restaurant tracks the orders of three types of meals (Vegetarian, Non-Vegetarian, and Vegan) during two meal times (Lunch and Dinner). The data is summarized below: Lunch Dinner Row Totals Vegetarian 50 30 80 Non-Vegetarian 40 50 90 Vegan 20 10 30 Column Totals 110 90 200 Use this data to answer the following three questions. Round probabilities to two decimal places.

A survey about preferred modes of transportation was conducted only among individuals who commute by car. Under which of the following conditions could the results still be considered valid?

Scenario: Restaurant Meals What is the probability that a randomly selected order was placed during Lunch?

A population has 20 AA, 50 Aa, and 40 aa individuals. How many A alleles are present?

In this pedigree, a circle = female, and a square = male. Assume all individuals are homoplasmic, but people from different families have different DNAs.    Assume that individual I-2 has a mitochondrial disease. How many of her six children will be affected with this disease?

In a mixed-sex population in Hardy-Weinberg Equilibrium, the frequency of colorblind females is 1%. Color-blindness is an X-linked recessive trait. Colorblind males in this population consist of:

In cytoplasmic inheritance, reciprocal crosses

The genotypic frequencies of AA, Aa and aa are 0.3, 0.2 and 0.5, respectively. Therefore:

According to the endosymbiotic theory the ancestors of chloroplasts are

The phenomenon of anticipation is characteristic of
