(10 points) A gene has 50 alleles. How many possible genotypes can exist in a population where all the 50 alleles occur?

The number of a possible genotype can exist is 2.6 trillion.

Explanation:

Considering that each locus of the allele can produce approximately 1275 genotypes.  The number of a possible allele combination at 4 loci is 1275 * 1275 * 1275 or about 2.6 trillion possible genotype

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

airlines i think? or a cruise boat? does this work out for u? ?
