Answer:

Given:

Parental generation

                       Homozygous dark chocolate easter bunny (WW) = dominant
                       Homozygous milk chocolate easter bunny (ww)   = recessive         

According to Mendel law of segregation
                   
Phenotype          Homozygous dark        x        Homozygous milk
 
Genotype                    WW                                       ww

Gametes                     W, W                                     w, w

F1 generation                               Ww, Ww, Ww, Ww

Result:
             All are heterozygous dark chocolate easter bunny (Ww).

F1 x F1 
     
Phenotype                    Heterozygous dark   x      Heterozygous dark

Genotype                                  Ww                                   Ww

Gametes                                   W, w                                    W,    w

F2 generation                            WW, Ww, Ww, ww

Result:

                 Homozygous dark (WW) = 1
                 Heterozygous dark (ww) = 2
                 Homozygous milk (ww) = 1

The offsprings of the cross between a homzygous milk chocolate easter bunny and a homzygous dark chocolate easter bunny will be dark chocolate.

  • This question involves a gene coding for chocolate color in easter bunny. The allele for dark chocolate is said to be dominant over milk chocolate.

  • A dominant allele is that allele that masks the physical expression of another in a gene. This means that the trait encoded by the dominant allele will be expressed over the recessive allele.

  • In a cross between a homzygous milk chocolate easter bunny and a homzygous dark chocolate easter bunny, the dark chocolate will be expressed over the milk chocolate because it is dominant.

  • Therefore, the offsprings of the cross between a homzygous milk chocolate easter bunny and a homzygous dark chocolate easter bunny will be dark chocolate.
