b. 3:1
that's the answer

Answer:

Option B, 3 : 1

Explanation:

It is given that

H - represents the shiny object allele

h - represents the dull object allele

Also H is dominant over h

Now punnet representing the the cross between parents having genotype "Hh" is as follows -

H h

H HH Hh

h Hh hh

Out of four allele, only genotype "hh" represents the phenotype of dull object.

Hence, phenotype ratio is as follows -

Shiny object : dull object

3 : 1

Hence, option B is correct
