it will make the populations numbers start to dwindle and it will get to the point of extinction
It can also be called a theory or a guess
Nucleotides in DNA are like the phospholipids in fats or quarks in protons. Nucleotides are the building blocks of DNA.
Answer:
Crossing over is the phenomenon by which homologous chromosomes exchange DNA segments between them during the process of meiosis.
If crossing over did not occur, there will be no genetic variation among parents and offsprings.
If the process of meiosis did not occur, there will be lesser chances of genetic variations to occur. Each chromosome will be either from the father or the mother with no genetic diversity present in it. As a result, genetic diversity will reduce.
