What is an Asymmetric Karyotype Males have XY sex chromosomes and females have XX sex chromosomes. Does the chromosome contain a single strand or multiple strand of DNA? The substance composing chromosomes is known as chromatina nucleoprotein, composed of nucleic acids and protein. In this study, the microscopic image of the complete blade cross section was realized using X-ray micro . The pairs of autosomes are called "homologous chromosomes." Homologous chromosomes have all of the same genes arranged in the same . What do you mean by permeability of membrane? From largest to smallest, the order of the set is 0.7, 0.33, 0.045. But, it has more acrocentric chromosomes. In addition, karyotypes help in the identification of chromosomal aberrations. To sort the chromosomes, a cytogeneticist will compare chromosome length, the placement of centromeres (the areas where the two chromatids are joined), and the location and sizes of G-bands. The sex chromosomes are called X and Y. Shape 5.
