Answer:
Dominant
Explanation:
Let the allele for short tail trait be represented by "T" and allele for long tail trait be represented by "t"
When a short tailed mutant with genotype "tt" is mated with long tailed mouse, following offspring will be produced -
Tt * tt
Tt, Tt, tt, tt
so the ratio of short tailed and long tailed mouse is 1:1
Here it is given as 4:3 . Hence, there are chances that short tail trait is dominant
In the second generation , two short tailed mouse are crossed. The following offspring will be produced
Tt * Tt
TT, Tt, Tt, tt
The ration of short tailed and long tailed mouse is 3:1
Here it is given as 6:3 i.e 2:1 . Hence, short tail trait is dominant over long tail trait.

Answer:
Observations at different distances show galaxies of different ages and therefore different stages of evolution. Observations of those different galaxies helps us to learn abt galaxy evolution because observations of distant objects reveal them as they were in the past.
