Week 3 Assignment
Please thoroughly answer the following 5 questions.
1. By conducting testcrosses, researchers have found that the sweet pea has seven linkage groups. How many chromosomes would you expect to find in leaf cells? The cell leaf would be able to contain 14 chromosomes within the sweat pea. The sweat pea should have seven chromosomes per set. The sweet pea should contain two sets of chromosomes.
2. Explain why inversions and reciprocal translocations do not usually cause a phenotypic effect. In a few cases, however, they do. Explain how.
Inversions and reciprocal translocations do not usually cause a phenotypic effect because of the person who is possessing these are able to equal the look alike numbers genetic components as a ordinary person. They would be able to possess a regular phenotype. It is also possible that the disengagement of the position of the chromosomes was able to influence the gene that was attempting to be expressed.

While conducting field studies on a chain of islands, you decide to karyotype two phenotypically identical groups of turtles, which are found on different islands. The turtles on one island have 24 chromosomes, while the turtles on another island have 48 chromosomes. How would you explain this observation? How do you think the turtles with 48 chromosomes came into being? If you mated the two types of turtles together, would you expect their offspring to be phenotypically normal? Would you expect them to be fertile? Explain.
Judging by the information provided it would seem as if the turtles would be linked together as they would both be in the polyploid haploid set family that would be both the 24 chromosome turtles and the 48 chromosome turtles. It is possible that this type of polyploid would have to be a tetraploids due to the parents. The children would have a normal phenotype and would be triploid and the triploid offspring would need to be
