In mice, a short-tailed mutant was discovered. When it was crossed to a normal long-tailed mouse, 4 offspring were short-tailed
skad [1K]

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.
