Even in the absence of genetic recombination, meiosis is an important source of genetic variation in sexually reproducing organisms. Use as an example a species with 2n=8, and an individual of that species that is a quadruple heterozygote for loci A, B, C, and D, with each loci on a different chromosome. Determine how many different types of gametes this individual can produce, and explain how segregation and independent assortment mechanisms produce genetic variation in the gametes produced by this...

Even if no recombination occurs, meiosis is an important source of genetic variation in sexually reproducing organisms. Excluding recombination, identify the key events in meiosis that result in segregation and independent assortment and how these two mechanisms produce genetic variation in the next generation. Use the following terms in your response: genes; alleles; homologous chromosomes; non-homologous chromosomes. (Drawings are encouraged.)

30. What is the source of genetic variation? How does meiosis contribute to the maintenance of genetic diversity? 31. Describe the preconditions for natural selection to operate and what the results of the natural selection will be. 32. Use the HW equations to solve simple population genetics problems with and without selection. 33. Hardy-Weinberg equilibrium tells us the conditions under which populations will not evolve. So what types of things may lead to a population evolving? How do these things...

What is crossing over? How is meiosis related to this phenomenon?

Explain in detail the process of meiosis including the significance of tetrad formation, crossing over, and the Law of Independent Assortment in maintaining chromosome number and genetic variability. Explain the key features that make it different from mitosis.

Explain how crossing over and independent assortment contributed to genetic variation. Your explanation should be based...

Explain how crossing over and independent assortment contributed to genetic variation. Your explanation should be based on ONE (1) living organism (you may choose any species that undergoes sexual reproduction as an example, except human). The details of explanation should be concise and informative. The length of the explanation should be less than 500 words.

1) Explain how this cellular mechanism affects variation: Crossing over Briefly explain how the mechanism (crossing over) could contribute to genetic variation in offspring. Be specific how this mechanism gives this result, when it occurs during the cell cycle, and be specific as to the type of genetic variation produced (from base-pair sequences to whole genomes).
