variation Flashcards
what is discontinuous data
there are no in-between data. ( like blood type)
what is a continuous data
there are no definite class ( like height)
reasons of variation
different genotype
difference of environment
mutation
cause of mutation
radiation cause-effect nucleus and so there the base sequence is different
what is an adaptive feature
an inherited feature that helps an organism to survive and reproduce in its environment
process of adaptation
populations become more suited to their environment over many generations, which is resulted from the process of natural selection
what is an artificial selection
breed the animal with advantages we want but not the animal that is not helpful to us.
process of meiosis that result variation in a species
meiosis produces gametes that are haploid
the gametes produced are all genetically different
during fertilisation, the fusion of the gametes at random produces a diploid zygote
this sexual reproduction results in variation in offspring and its parent
