Impacts of Genetic Engineering on Biodiversity
Genetically engineered crops include varieties of corn, cotton and potatoes. These plants have a bacterial gene from Bacillus thuringiensis (Bt) inserted into their genome. The Bt gene codes for the...

Did Heterotrophs Evolve From Autotrophs?
Scientists have overwhelming evidence to show that all species now alive on Earth evolved from a common ancestor; but figuring out where that common ancestor came from or how it originated is a...

Dominant Physical Genes in Humans
Genes determine the physical traits that we see in each individual. They are segments of DNA that contain information that code for proteins in the body and some of these proteins determine our...

About Biofuel Farming
Biofuels have the capacity to change the way the wold uses energy -- but farming for biofuels may also pose some serious consequences. Farmers grow "biomass feedstocks," or plant materials and algae...

Mendelian Vs. Modern Genetics
Mendelian genetics and modern genetics are really just parts of the same thing. Gregor Mendel formed the basis of modern genetics. Later scientists built on his ideas and laws, elaborating on them....

What Is Pure Trait and a Hybrid Trait?
A diploid organism has paired chromosomes, each with a similar arrangement of genetic loci. Variations of these genes are called alleles. If an organism has one of the same type of allele on each of...

3 Stages of Interphase
During mitosis, or asexual cell reproduction, one cell splits into two. The process of mitosis has several stages; interphase is the first, and is itself divided into three separate stages. Each of...

Zygote Structure
The minuscule zygote is the beginning of a new person with unique genetics from both mother and father. The tiny structure has to divide over and over, though, before it is complex enough to attach to...

How Wings Are an Adaptation for Birds
Over millions of years, birds have perfected the body structure needed for flight. In fact, a bird's entire being has adapted to a life of soaring through the air. Besides insects and bats, no other...

Two Purposes of Mitosis
The value of mitosis to a human body is incalculable, because it is the way the body grows and also the way it repairs itself. Mitosis requires several steps to carry out these two vital functions, and...
