Which was a direct result of the human genome project?
(select all that apply.)

a)the routine test for genetic forms of breast cancer
b)the discovery of the genetic code
c)the discovery that humans have approximately 20,000 genes—far fewer than expected
d)the creation of pcr-based tests for many genetic disease

The correct answer is C) the discovery that humans have approximately 20,000 genes—far fewer than expected.

Explanation:

The human genome project was started in 1990 and completed in 2003 to identify all the DNA sequences and genes human body is made up of and to map all the genes present in the human body.  

The great achievements of this project were identification of more the 20 thousand genes, the discovery of genetic and physical map, Identification of DNA sequence present in genes with 99.99 % accuracy.

The human genome project is useful in the identification of genes related to genetic disease and helpful in curing these diseases by gene therapy and drug design.

So, the correct answer is C) the discovery that humans have approximately 20,000 genes—far fewer than expected.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
