Medical Genetics The haploid number is the number of chromosomes in a gamete. Usually, the diploid number is twice the haploid number

Medical Genetics A. heterchromatin and euchromatin The degree of condensation of the nuclear DNA is variable. Strongly condensed DNA is called heterochromatin, Less condensed one euchromatin. Heterochromatin is stained more intense than euchromatin by certain nuclear dyes
Medical Genetics Heterochromatin is the condensed form of chromatin organization It is seen as dense patches of chromatin

Medical Genetics Abundant heterochromatin is seen in resting, or reserve cells such as small lymphocytes(memory cells) waiting for exposure to a foreign antigen Heterochromatin is considered transcriptionally inactive
