In chickens, the black wing allele is co-dominant with the white wing allele. Black and white birds are homozygous for the black (B) allele or the white (W) allele.
In genetics the terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are being expressed separately to produce the different traits in the individual. In perfect dominance, only the one allele of the genotype is also present in the phenotype. In codominant cases, both the alleles of the genotype are present in the phenotype. In the case of the imperfect dominance, the phenotype shows the mixture of genotypic alleles. In the genetics terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are expressed and separately to produce the different traits in the individual.

Answer:The best explanation is;
The materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials
Explanation: A protoplanet is an embryo formed in a protoplanetary disc which has passed through a melting phase that enables the formation layered interior
In protoplanets the effects of partial melting of the components due to heating produced by radioactive decay and pressures from forces of gravity there is segregation of the melt and igneous composition such that the heavier melted metal can sink and be over laid by the lighter igneous rocks
Therefore, the best explanation is that the materials undergo decay when they collide, which results in the heating and subsequent melting and segregation by the sinking of the heavier melted materials and rising of the lighter igneous materials.
