Here we have the alleles H - no horns and h - horns, and the individuals that have horns (hh) are represented in the pedigree with a red filling.

• The parents in generation, ,I, ,are ,hh (I-1) , and ,HH (I-2),, so all of their children in generation II will be ,Hh, ,(II-2, II-3, II-5),.

,

• II-4, ,is red,, so it has a ,hh, genotype.

,

• II-1 y II-2 have no horns, but one of their children does ,(III-3, hh),, which means, II-1, also carries the recessive allele ,(Hh,).

,

• III-4, ,is red,, so it has a ,hh, genotype

,

• III-5 is Hh, because their mother is hh.

In summary, the genotypes would be as follows:

Generation I:

0. hh

,

1. HH

Generation II:

0. Hh

,

1. Hh

,

2. Hh

,

3. hh

,

4. Hh

Generation III:

0. HH

,

1. Hh

,

2. hh

,

3. hh

,

4. Hh
