1. Jordan gave blood at the school blood drive and was very upset to learn that they had Type O blood, because both of their parents had Type A blood. Draw a Punnett Square to help Jordan understand if they should be concerned or not.

2. Parents have three children - one with Type O blood, one with Type A blood, and one with Type AB blood. Based on their offspring what are the genotypes of the parents?
A. IAIB and ii
B. IAi and IAIB
C. IAi and IBi
D. ii and IAIA

3. Based on the parent genotypes shown what are the probabilities of each blood phenotype, written as a ratio?

Parent 1 Genotype
IBi
Parent 2 Genotype
IAIA

A. 1 Type A : 1 Type B : 1 Type O : 1 Type AB
B. 1 Type A : 0 Type B : 2 Type O : 1 Type AB
C. 1 Type A : 0 Type B : 0 Type O : 1 Type AB
D. 1 Type A : 0 Type B : 0 Type O : 0 Type AB

A. 0%
B. 25%
C. 50%
D. 100%

5. Hemophilia is a sex linked recessive trait. What is the probability, expressed as percentage, of a couple having a female offspring with hemophilia if the male parent does not have hemophilia and the female parent is a carrier?
A. 0%
B. 25%
C. 50%
D. 100%

6. In fruit flies eye color is a sex linked trait where red eyes are dominant to the white eye phenotype. If a male with red eyes is crossed with a purebred white eye female, what is the ratio of eye color and sex phenotypes for their offspring?

A. 1 red eye female : 0 white eye female: 0 red eye male : 1 white eye male
B. 2 red eye female : 1 white eye female: 0 red eye male : 1 white eye male
C. 1 red eye female : 1 white eye female: 1 red eye male : 1 white eye male

I’m not really sure

Answer from: Quest

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar flies (drosophila). one sample revealed an anomaly: a white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs) produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
