A table represents the possibility of an association between eye color and hair color. Hair Color Eye Color Brown Black Green 22 15 Blue 18 19 In order to determine if there is a significant difference between eye color and hair color, the chi-square test for association and independence should be performed. What is the expected frequency of Blue Eyes and Black Hair? a.) 20 b.) 17 c.) 19 d.) 18

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female? B. b,...

In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Of only the offspring that have brown eyes and brown hair (B_H_, where dash indicates that the individual could be either homozygous or heterozygous for the dominant allele), what proportion are expected to have a genotype that is heterozygous for one of the traits but homozygous for the other trait? A) 1/4...
There are 24 people. 9 have green eyes, 4 have brown eyes, 5 have hazel eyes, and 6 have blue eyes. 3 people are then selected at random without replacement. What is the probability that 2 people selected have the same eye color, and that the other person selected has a different eye color
Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...
For the purpose of this problem assume that in humans eye color is controlled by a single gene and that the allele for brown eyes is dominant to the blue-eye allele. Two brown-eyed parents planning a pregnancy already have a blue-eyed daughter. PLEASE NOTE: gender (being male or female) is a SECOND trait (like a second Punnett square), but no need for a Punnett square because the chance that an offspring will be male or female is always 1/2. Assign...
Suppose chromosome Ace includes the gene for hair texture, chromosome 2 has a gene for eye color, and chromosome 3 has a gene for nose width with the traits for each shown in the table. BLACK cards carry the dominant allele and RED cards carry recessive allele.

In a population of interest, we know that, 77% drink coffee, and 23% drink tea. Assume that drinking coffee and tea are disjoint events in this population. We also know coffee drinkers have a 30% chance of smoking. There is a 13% chance of smoking for those who drink tea. a. (2 points) Five individuals are randomly chosen from this population. What is the probability that four of them drink coffee?
