The STR DNA marker DS11 is located on the p arm of the chromosome #8 in humans. Molecular analysis has shown that Charlie Chaplin is a heterozygote for the STR marker (genotype DS11A and DS11B) Using this knowledge, provide a diagram of meiosis showing only the movements of chromosome 8 (assume no nondisjunction). Throughout, indicate where the marker may be found (in other words, label the chromosome to show where the STR markers can be found. please only show the chromosomes at interphase, metaphase 1, end of meiosis 1, metaphase 2, and end of meiosis 2.

The pedigree shows individual  1 and 2

Thank you for the follow-up! So, in what sort of conditions would there be an extra Y chromosome? If it's not there in the first place.. how can it get transversed/moved to another chromosome? Unless it is duplicated?

Hi, could your please answer this question? I'm so confused.  The following diagram (picture added) shows 2 pairs of autosomal chromosomes in a karyotype of a biological woman. Based on the karyotype, a genetic counselor determined that there is evidence that a translocation occurred between two non-homologous chromosomes. The other 21 pairs of chromosomes are NOT shown in this diagram. Assume no chromosomal aberrations occurred in the other chromosomes. As a student-researcher, what would be your answer if the genetic counselor asks you if you can determine whether the translocation occurred in a somatic cell, germ-line cell, or whether this can even be determined from the figure? provide the reasoning for your answer.

Need help, please.

GENETICS In a sexually reproducing diploid organism in which 2n=6, a normal meiocyte in reduction should exhibit a total of 3 bivalents at the metaphase plate. Consider the following organism in the previous statement. if there is no crossing over, the number of possible haploids (gamete) genotypes generated by "chromosome shuffling" during meiosis is _____?
