Retinitus Pigementosa is a result of a mutation in the rhodopsin gene and can result in blindness if such mutation occurs. (http://www.ncbi.nlm.nih.gov/protein/4506527) Further information on the disease " it is an inherited progressive disease, inherited either autosomal recessive or autosomal dominant" is also provided by (http://www.ncbi.nlm.nih.gov/protein/4506527)

The process of [[Meiosis|meiosis]] contains two meiotic divisions. Within the first meiotic division, the first of four stages, [[Meiosis prophase 1|Prophase (I)]] contains five substages itself, and the first substage is Leptotene. As stated by Hartl et al (1) The substage Leptotene, is where the [[Chromosome|chromosomes]] first become long, thin, visible structures. Leptotene is regarded as the initial phase of chromosomal condensation, where the pair of [[Sister chromatids|sister chromatids]] become visible under an electron microscope.  (2) "In this initial phase of chromosome condensation, numerous dense granules appear at irregular intervals along their length. These localised contractions called ''chromomeres'' have a characteristic number, size, and position in a given chromosome."
