Answer:
The genes are linked and 10 mu apart.
Explanation:
A female AaBb rabbit is test crossed with a male rabbit (aabb). The male can only produce<em> ab</em> gametes (all the progeny will have ab on one of the homologous chromosomes).
If the genes assorted independently, the female would produce 4 types of gametes with the same frequency: 1/4 AB, 1/4 Ab, 1/4 aB and 1/4 ab.
However, the observed AB and ab gametes were much more frequent than Ab and aB, which means that the genes are linked and alleles on the same chromosome do not assort independently during meiosis.
Recombination is a rare event, so the most abundant gametes are the parentals. That is how we know that the mother had the AB/ab genotype. The recombinant gametes therefore are Ab and aB.
Distance (mu) = # Recombinants × 100/ Total progeny
Distance = (54 + 46) × 100/ 1000
Distance = 100 × 100/1000
Distance = 10 mu
From the earliest moments of life, the interaction of heredity and the environment works to shape who children are and who they will become.
The complex interaction of nature and nurture does not just occur at certain moments or at certain periods of time; it is persistent and lifelong.
During anaphase, homologous chromosomes separate and head towards opposite poles of the cell.
- A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase.
- After the metaphase procedure, the mitotic stage known as anaphase occurs during which the freshly replicated chromosomes are transferred to the opposing poles of the cell and the replicated chromosomes are split.
- Sister chromatids split from one another and are drawn to the opposite ends of the cell during anaphase.
- The sister chromatids are able to separate because the protein "glue" holding them together is degraded.
- Each chromosome now exists on its own. Each pair's chromosomes are drawn to the cell's opposite ends.
