i believe it is crossing over
True
Genetics is the study of heredity and the variation in organisms. When studying genetics, you learn about dominant and recessive traits along with much more.
fusion of gametes via fertilization
A variation of a gene is called and allele. Different alleles are caused by mutations.
Genetic variation is one of the conditions required for Natural Selection to occur.
i believe it is crossing over
True
Human recombination is a significant source of genetic variation.
It increases genetic variation in organisms
Basic source of variation in all organisms is mutation .
No.
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Yes.
meiosisHuman recombination
True yes
Well, if an organism reproduces asexually then it only has the genetic information from itself to use in creating a new organism. With sexual reproduction, the organism has the genetic information from more than one organism to use, which produces more varied organisms, and it becomes more varied the more different genetic information is used over generations.
