Answer:

When a single gene is responsible for controlling multiple traits then the gene is said to be pleiotropic.

Explanation:

A pleiotropic gene is a gene that controls many functions and thus, a mutation in this single gene is going to show its effect in several traits.
Since, the gene responsible for white fur in cats is also responsible for eye colour and hearing and thus, it controls more than one trait and hence, it is pleiotropic.

How are the careers of environmental activist, environmental lawyer, and environmental journalist similar

Elan Coil [88]

An Environmental Activist is a broad term for someone who is actively engaged in fighting for the environment. It could even be said that both environmental lawyers and environmental journalists are environmental activists in their own rights. However, someone could still be an activist without being a journalist or a lawyer, and this activist may be involved in fundraising, petitioning, and actively protesting. Environmental journalism is quite self explanatory; to report though written and/or verbal media to spread information on issues pertaining to the environment. An environmental lawyer fights legal battles to ensure dangerous actions are prevented or held accountable, and may also impact future legislation regarding environmental management.
