The green alga Caulerpa is an invasive species that has moved from tropical coastal waters to cooler and more temperate ocean areas. What impact has Caulerpa had on ocean biodiversity in its non-native habitat?

Explanation:

Caulerpa alga is a genus of seaweeds in the family of Caulerpaceae (green algae). They are uncommon in nature because they consist of only one cell with multiple nuclei, and known as the biggest single cells in the world.

When introducing Caulerpa algae to a non-native area, it can displace native algae and negatively affects the coastal ecosystem, and affect the species living in the area such as invertebrates, fish, marine mammals, and sea birds, etc.

you know they are heterozygous for a trait because they have it as jj or jj.
