Answer:

In a homozygous state, the allele "P" is lethal. Those individuals with PP genotype will be born dead.

Explanation:

The allele P is dominant over p and expresses the trait "platinum". But in the homozygous state, it is mortal, PP.  The allele p expresses the "Silver" trait.

This is:

  • For platinum individuals, the genotype  should be Pp
  • For silver individuals, the genotype should be pp
  • For dead individuals, the genotype should be PP.

So in the crosses, the punnet squares are:

1- Silver x Silver

     Parental)          pp     x     pp

     Gametes)       p    p         p   p

     Punnet square)    

                                      p             p

                              p     pp           pp

                              p     pp           pp

     

       F1 Genotype) 100 % recessive homozygote pp

2-  Silver x Platinum

     Parental)          pp     x     Pp

     Gametes)       p    p         P   p

     Punnet square)    

                                       p             p

                              P     Pp           Pp

                              p    pp           pp

     

       F1 Genotype) 50 % recessive homozygote pp,

                              50% heterozygote for the trait Pp

3- Platinum x Platinum

     Parental)          Pp     x     Pp

     Gametes)       P    p        P   p

     Punnet square)    

                                       P             p

                              P     PP           Pp

                              p     Pp           pp

     

       F1 Genotype) 25 % recessive homozygote pp

                              50% heterozygote for the trait Pp

                              25% dominant homozygote PP. This is a dead          

                                   individual.

In this last cross, individuals with genotype PP dye, so, of the whole offspring, there are two platinum for each silver offspring.
