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.   Illustrate the source of aneuploidy if it occurs in Meiosis I. Diagram spermatogenesis starting with the primary spermatocyte up to spermatozoa, making sure to distinguish between chromosomes and the different phases of meiosis I (prophase I*, metaphase I, anaphase I, telophase I). Indicate the respective chromosome equation and chromosome number of the primary spermatocyte, secondary spermatocyte, spermatid, and spermatozoon.

Question

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.

 

  1. Illustrate the source of aneuploidy if it occurs in Meiosis I. Diagram spermatogenesis starting with the primary spermatocyte up to spermatozoa, making sure to distinguish between chromosomes and the different phases of meiosis I (prophase I*, metaphase I, anaphase I, telophase I). Indicate the respective chromosome equation and chromosome number of the primary spermatocyte, secondary spermatocyte, spermatid, and spermatozoon.
