You and a friend are in line for a movie when you notice the woman in front of you sneezing and coughing. both of you have been equally exposed to the woman's virus, but over the next few days, only your friend acquires flu-like symptoms and is ill for almost a week before recovering. which one of the following is a logical explanation for this?
a. you have an innate immunity to that virus.
b. you have an adaptive immunity to that virus.
c. your friend has an autoimmune disorder.
d. your friend has allergies.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

we would need to see the picture to answer it

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
