I think it is a petrified fossil but you didn't give any choices
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.

The correct answer is somatic symptom disorder.
This refers to a disorder when you feel discomfort or pain, however, there is no explanation for it given that the scans show no problems with your body. It may seem that it is all in your head because you will keep going to doctor trying to find a cure for something that ultimately doesn't exist.
They will slowly die off and go into extinction like mammoths. Hope this helps! ;D
