I believe the correct answer is A
I believe the answer is:
Aristarchus
Copernicus
Galileo
In the past, most people believed that the earth is the center of the universe. This teaching is supported by the churches without many people dare to oppose the view. All of the three scientists mentioned above provide proofs that sun is the center of the universe and the earth is just revolved around it.
Well, I'm pretty sure it's the same reason as to why we call other people only by their first (or last) name: to simplify the name.
(e.x. someone called Sarah Wells would just be called Sarah.)
Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.
