Organism in the phylum Chordata develop dorsal nerve cord in their embryonic stage. Development of dorsal nerve cord is the characteristic feature of these animals and is developed by the mesoderm layer. In many of them they are only present in embryonic stage.

In vertebrates notocord disappears after completion of embryonic stage and is replaced by vertebral column which provide support and anchor to the  body structure of vertebrates.

A black guinea pig crossed with a guinea pig with albinism produced 12 black offspring When the albino was crossed with a second
givi [52]

Albinism is a recessive trait. It is expressed only in an individual's genotype contains a pair of the recessive allele 'a', that is responsible for causing albinism.

Black skin color in guinea pig is a dominant trait which does not allows the recessive trait to be expressed.

Thus, guinea pigs having the genotype 'aa' will exhibit albinism while those having the dominant allele for black color will have black skin color.
