The seeds fly everywhere so therefore it is logical
Hydrogen,ammonia,methane,water
Their reproductive isolation from each other is complete: False
They are unable to produce hybrid offspring upon interbreeding: True
They shared a common ancestor recently in evolutionary time: False
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
Genetic alteration refers to altering DNA sequence. Gene alteration forms genetically modified products that modifies the gene sequence. DNA consist of two long chains of nucleotides that are twisted and joined together in hydrogen bonds. These DNA cannot be altered in nature but gene expression can be altered.
