if gametes from a gene pool combine randomly

If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage the allele will likely eventually disappear due to natural selection. In natural selection allele frequencies change because some alleles confer higher fitness, whereas in genetic drift allele frequencies change because of chance sampling error. Explain. Any of the 64 distinct DNA sequences of three consecutive nucleotides that either, Q:Below is the 53 strand of a double-stranded DNA molecule with the following nucleotide d. All of these are correct. They undergo meiotic drive, such that when a heterozygote produces gametes, they are not in the expected 50/50 ratio. An individual has the following genotypes.

If there is more variation, the odds are better that there will be some alleles already present that allow organisms to survive and reproduce effectively under the new conditions. The genome is the collective term for all the genetic material in a cell. If gametes from a gene pool combine randomly to make only a small number of zygotes, the allele frequencies among the zygotes may be different than they were in the gene pool because: A) The effects of natural selection are more pronounced in small populations.

This gene comes in a white allele, Phenotypeflower color It does not seem to serve any function as far as I know. In fact, the evolutionary trajectory of a given gene (that is, how its alleles change in frequency in the population across generations) may result from several evolutionary mechanisms acting at once. of w = 10/18 = 0.56. To predict this, we need to make a few assumptions: First, let's assume that none of the genotypes is any better than the others at surviving or getting mates.
