Biology
Orangutans are an endangered species in their naturalenvironment (the islands of Borneo and Sumatra), so acaptive-breeding program has been established by using orangutanscurrently held in zoos around the world. One component of thisprogram is cytogenetic research. This research has shown thatorangutans from the two islands have different forms of chromosome2. Before this cytogenetic difference became known, some matingswere carried out between animals from different islands, and 14hybrid progeny are now being raised in the breeding program.
What term/s describe the difference/s between thesechromosomes?
Draw the chromosomes 2 pairing of such a hybrid individual,during the first meiotic prophase.
In 40% of meioses, there will be a crossover somewhere in theregion between bands p1.1 and q1.2. Draw the chromosomes 2 gametesthat would result from a meiosis in which a single crossoveroccurred within band q1.1.
What fraction of the gametes produced by a hybrid orangutan willgive rise to viable progeny, if only these chromosomes differbetween the parents?
