A diploid species has 3 pairs of chromosomes in its somatic cells. In males, the first pair is large submetacentric[1]; the second is medium acrocentric[2], and the third is small telocentric[3]. In females, the first two pairs are like those of the males while the third is large metacentric[4][5], with satellite4 Illustrate the karyograms (drawing/picture of the chromosome) of the following:
A triploid cell in females
tetrasomic cell in males
tetraploid cell in females
[1] submetacentric --centrosome is just above the middle of the chromosome
[2] acrocentric --centrosome is much higher location than submetacentric so that the “p” arm of the chromosome is much shorter than the q arm
[3] telocentric --the centromere is at the end of the chromosome
[4] metacentric --centrosome is in the middle of the chromosome; thus the “p-arm” and the “q-arm” or both arms of the chromosome are equal in length

Identify the type of chromosomal aberration described in each of the following cases and provide and example.
loss of a chromosome segment
extra copies of a chromosome segment
reversal in the order of a chromosome segment
movement of a chromosome segment to another, non homologous chromosome
Consider a diploid organism that follows the XX-XO mode of sex determination. Normally, there are 7 chromosomes in its somatic cell. The chromosomal composition is as follows:
Chromosome I is a large acrocentric chromosome
Chromosome II is a large telocentric chromosome
Chromosome III is a small telocentric chromosome
Chromosome IV (X chromosome) is a medium submetacentric chromosome
Aneuploidy was observed in a particular individual wherein there are three copies of Chromosome III.
Diagram how aneuploidy may occur through Mitosis starting from a parent cell at G1 phase. Make sure to distinguish between chromosomes and the following phases of cell division (G1 phase, prophase, metaphase, anaphase, telophase, cytokinesis). Indicate the chromosome equation and chromosome number of the parent cell and the daughter cells. *S phase and G2 phase purposefully excluded

- In a germline progenitor cell before DNA replication (2N), a translocation occurred between a telocentric and submetacentric chromosome resulting in a translocation heterozygote. The location of the translocation is illustrated below. Draw the Prophase I pairing conformation that would result from this translocation. The four types of chromosomes you have now can be labeled as follows: T-WT (telocentric wild type), T-TL (telocentric translocation), SM-WT (submetacentric wild type), and SM-TL (submetacentric translocation). Using these labels, list (please do not draw) the possible outcomes of Anaphase I and the possible phenotypes for each outcome.

- crossing over within a pericentric inversion produces chromosomes that have extra copies of some genes and no copies of other genes. The fertilization of gametes containing chromosomes with duplications or deletions often result in children with syndromes characterized by developmental delay, intellectual disability, abnormal development of organ systems, and early death. Maarit Jaarola and colleagues examined individual sperm cells of a male who was heterozygous for a pericentric inversion on chromosome 8 and determined that crossing over took place within the pericentric inversion in 26% of the meiotic divisions (M. Jaarola, R. H. Martin, and T. Ashley. 1998. American Journal of Human Genetics 63:218–224). Assume that you are a genetic counselor and that a couple seeks counseling from you. Both the man and the woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this…arrow_forwardReferring to Figure 17-19, draw a diagram showing theprocess whereby an inversion formed from crossing overcould generate a normal sequence.arrow_forwardRice has a chromosome number of 2n = 24.
