Galaxy is a collection of stars, gas, and dust bound together by gravity. The smallest galaxies may contain only a few hundred thousand stars, while the largest galaxies have thousands of billions of stars.
Here, R is dominant over r.
Now, RR × Rr cross, results in:
2 RR & 2 Rr
So, genotypic ratio = RR : Rr = 1:1
Phenotypic ratio = Dominant : Recessive = 1:0
Hope this helps!
