In Drosophila, the linked mutations ebony body color (e), rough eyes (r), and brevis bristles (b), are autosomal recessive. A test cross yielded the following results: wild type 169
ebony 619
ebony, rough 9
brevis 14
rough 93
ebony, brevis 97
rough, brevis 621
ebony, rough, brevis 165
Total 1787
1: Which locus is in somewhere between the other two?
a. ebony
b. rough
c. brevis
d. wild type
e. can not be determined from the information provided
2: What is the percentage of double cross overs?

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 : )

yes

no

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
