Consider 2 genes in peas- gene controlling seed color- yellow Vs green; gene controlling seed texture-smooth Vs wrinkled. Assume
the two genes are very tightly linked. A true breeding smooth green plant is crossed to a true breeding wrinkled yellow. All the F1 progeny were smooth yellow. The F1 generations were self-fertilized. In the F2 what is the expected ratio of the phenotypes- Smooth & yellow: smooth & green: wrinkled & yellow: wrinkled & green
Curious enough, the smallest galaxies are also the elliptical types. The oldest and farthest galaxy ever discovered is an irregular type of galaxy called GN-z11. It is 32 billion light-years / 9.8 billion parsecs away from us. It is estimated that the galaxy formed just around 400 million years after the Big Ban
