What is Vulnerable Species

A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature that is threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home.

    But before a germ cell splits, each chromosome swaps a chunk of itself with its partner chromosome in a process called recombination or "crossover," because segments of DNA cross over between chromosomes in a pair. As a result, offspring won't have chromosomes identical to that of their parents.

BIOLOGY

a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g.  Wise Sapiens.
