Industry:Natural environment
A heteromorphic chromosome that plays a role in sex determination, such as the X and Y chromosomes, whose distribution in a zygote determines the sex of the organism; a chromosome whose DNA determines sexual characteristics in females (X)-and males (Y).

The water moves through a network of subterranean and surface drainage pathways which converge into streams and rivers, eventually reaching an estuary and finally the ocean. Because water moves downstream, any activity that affects the water quality, quanity, or rate of movement at one location can affect locations downstream to the ocean and out to coral reefs.
Industry:Natural environment
Any eukaryotic DNA sequence that initiates and supports chromosomal replication; also called autonomous(ly) replicating segment.
Industry:Natural environment
