How is it possible that a parent with blue eyes and wet ear wax, and another parent with brown eyes and dry ear wax, have a child that has blue eyes and dry ear wax?

Answer:

2 different types of genes are given,

long lash (L) and short lash (l)

wet ear wax (W) and dry ear wax ( w)

here two heterozygous individuals are crossed

LLww × llWW

        ↓

    LlWw    ( F1 gen)

        ↓

(1)  LL  (2) Ll   (1) ll    [ as 1:2:1 ( 1= dominant and recessive but 2= hybrid)]

(1) WW (2)  Ww (1) ww

         ↓

1 LLWW   2 LLWw   1 LLww

2 LlWW  4 LlWw   2 Llww

1 llWW     2 llWw    1 llww

therefore,

long lash and dry ear wax = LLww (1) + Llww (2)

                                     =  3/16

there is a 3/16 chance that the child will have long eyelash and dry ear wax.

Answer:

I don’t really understand the question you asked...but the child inherited the eyes of the 1st parent and the ear wax of the 2nd parent. Another way could be possible too. The child could inherit brown eyes and wet ear wax.

Explanation:

Variation at a single gene determines which kind of earwax you have; the allele for wet earwax is dominant over the allele for dry earwax. The allele for dry earwax appears to have originated by mutation in northeastern Asia about 2,000 generations ago, then spread outwards because it was favored by natural selection.
