Is it true that meiosis and the joining of gametes generate genetic variation in offspring?
true
What is the ultimate souce of genetic variation and the basis for the diversity of life on earth?
Interchange of genetic material during meiosis and random union of male nad female gametes during fertilization.
What is produced by the end of the?
Gametes, haploid cells. They have half of the genetic material in the original cell. They're genetically different due to cross over and independent assortment - to create variation.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
How does meiosis contribute to the variation in a species?
During meiosis crossing over takes place between homologous chromosomes. Thus genetic material get interchanged and 50 % new combinations are obtained after each meiotic cell division. Thus, meiosis brings heritable variation in the gametes.
Is it true that meiosis and the joining of gametes generate genetic variation in offspring?
true
What does meiosis do for species?
Meosis creates gametes (reproductive cells) and allows genetic variation of the species
Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
What happens after meiosis to introduce even more genetic variation in sexually reproduced organisms?
fusion of gametes via fertilization
How do gene frequencies change when there is no relationship between genetic variation and reproductive success?
Alleles that are neither selected for or against will remain at the same frequency in a population. (This assumes that the population is also large enough to not suffer from variation due to genetic drift.)
Principle of independent assortment?
Independent assortment is the random assortment of chromosomes during the production of gametes. This results in genetically unique gametes. The gametes are genetically different to the one another. This leads to genetic variation.
What is the difference between the genetic material in body cells and gametes?
Gametes only contain one half the total genetic information.
What is the ultimate souce of genetic variation and the basis for the diversity of life on earth?
Interchange of genetic material during meiosis and random union of male nad female gametes during fertilization.
How does meiosis introduce genetic variation into offspring?
1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .Meiosis produces variation in gametes by crossing over & independent assortment also called reshuffling of genetic material . Such gametes after fertilization produce offspring with different characters .
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
How can prophase I and metaphase I in meiosis cause genetic variation in offerspring?
by being cheesy Edited answer: During prophase I of meiosis pairing among homologous chrosomes takes place. This is followed by crossing over. The recessive and dominant genes get interchanged during chiasma formation and such interchanged genetic material get separated in to different cells during mtaphase I. Hence, prophase I and metaphase I cause genetic variations in the male and female gametes. On randum mating among these gametes, genetic variation in the offsring are caused.
What is the relationship between sexual reproduction and genetic variation?
In sexual reproduction, two parents combine their geneticmaterial to form a new organim. Meanwhile, genetic variation can give the new organism a helpful trait or unhelpful trait that would affect its life and how it could life in a certain enviornment.
