The picture below represents a G1 cell from a newly discovered species that uses the X/Y sex
determination system. Alleles for the different autosomal genes of interest are indicated on the
chromosomes, and genes R and T are 16 cM apart. Red lines show maternal chromosomes, and blue lines
show paternal chromosomes. Answer the following questions about this individual.

a) Name any two loci in this individual that can result in recombination in the gametes via the process of
crossing over.
b) What is the sex of this individual? Justify your answer.
c) Give the term that will describe the morphology of the that carries the N alleles.
d) Provide the genotype of the fertilizing male gamete that produced this individual.
e) This individual can produce a pool of different gametes. List any TWO potential gametes that will occur
at different frequencies. Give the alleles of each gamete contained within a set of brackets, and indicate the
expected frequency (up to two decimals) at which that gamete would occur.
