D is correct answer because in Robertsonian translocation, one chromosome become attached to another chromosome which may be homologous or non-homologous.. As a result, a big chromosome form due to attachment of large fragments of chromosome and one become small due to attachment of small fragments.

You see a recombination frequency of 50% between two genes. Which of the following possibilities can you exclude? That the genes are located close together on the same chromosome That the genes are on different chromosomes O That the genes are assorting independently That the genes are located on the same chromosome, but very far apart Meiosis contributes to genetic diversity by: o Reducing the number of chromosomes for karyogamy (fusion of nuclei) with another gamete O Recombining homologous chromosomes...

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...
