COMMENTS:
The notation of human chromosomes’ can be represented in Braille’ notation. The human chromosome notation has microscopic levels BELOW:
Chromosome Groups: A, B, C, D, E, F, G.
Chromosome Numbers: X, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, Y.
Chromosome Arms: Top-short (“p”) arm. Bottom-long (“q”) arm.
Chromosome Regions: 1, 2, 3, 4.
The ABOVE human chromosome spread is known by both blind and sighted adults. The notation of chromosomal DNA is an easy concept that all students, blind and sighted must learn.
