The joining(fusion) of male and female
gametes causing mixture of genetic
material so variety in the offspring.
ASEXUAL
No fusion, only one parent ther is no mix of genetic
information so offspring contains no variation and
offspring is genetically identical so a clone.
GENETIC ENGINEERING
(GENE MANIPULATION)
Genes from chromosomes can be 'cut
out' using enzymes and transferred to
cells in other organisms.
Genes can also be transferred into plants,
animals or microrganisms as they start to
develop so they grow with desired
characteristics for example crops.
crops with modified genes are
called genetically modified
crops (GM crops)
Gm crops could be resistant to
insect attack or
herbicides(weed killers)
GM crops generally show
increased yields
Concerns about GM crops include effects on wild
flowers and wildlife also uncertainty about the
effects of eating GM crops on human health
