may111Participanthi i was wondering if anyone can help me;
why is principle of independent assortment in ensuring genetic fitness in a human? dont quite get this question- can anyone briefly explain what this means??AND see the question below, I HAVE answered nearly all of it just want to know what natural selection means and what do they mean by determining the outcomes of the crosses? CAN ANYONE JUST EXPLAIN SIMPLY WOT IT MEANS, YOU DONT HAVE TO ANSWER THE QUESTIONS!! I DONT GET GENETICS, SOO CONFUSING!
How do you think the progeny of your progeny will be in 6 generations (120 – 200 years)? Do you believe that natural selection, or behaviour of yourself and progeny will be the major factor in determining the outcomes of the crosses?

I think natural selection is at least not duch a great factor as earlier because human beings have found possibilities to evade it partly.

sorry, don’t know how to answer that question… BUT i can tell you what natural selection and independent assortment is.
Natural selection:
the major mechanism of evolution in any population. those individuals who are better adapted in a particular environment exhibit better reproductive success. they have more offsprin that survive and pass their genes on to more offspring.Independent assortment:
A process during metaphase one, which results in the recombination of unlinked genes.
Independent assortment, crossing-over, and random fertilization provide the shuffling of alleles during meiosis and fertilization.
