Does one gene control many traits or do many genes control one trait?
The answer is simple, genes are inherited and traits are your own uniqueness, genes will have an influence on your traits, so if you are a loud person, that will be one of your traits, and if a parent is a loud person, you will have most likely inherited that gene from them, so the answer is one gene controls many traits because the gene was there first
What does pleiotropy mean?
Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits (those you see). A series of defects that affect multiple systems but is caused by one defective gene.
What contain instructions for traits?
Alleles
What does a gene do in a organism?
A gene has all the traits of the organism
How does predation helps in the evolution of organisms?
Predation causes traits that enable prey to evade predators to be favoured in the population gene pool.
What are Mendelian traits?
Traits that are controlled a multiple gene loci. Polygenic traits.
What is the difference between single-gene traits and complex traits?
Single gene diseases only effect one typeof gene where im a complex genetic disease many genes are effected. An example of a single gene diseas is sickle cell anemia. Cancer would be an eexample of a complex gene disease.
What change in genes or chromosomes that causes a new trait to be inherited?
Mutations create variation in the gene pool by causing new traits to appear
What can occur for limited gene flow?
Mutations can occur in gene processing errors.
The traits of an organism are controlled?
Gene
What controls traits is organism?

What are the instructions for an inherited traits?
