Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I
Bogdan [553]

Answer:

<u>Sister chromatids are identical  forms of chromatids  of a chromosomes. They are mostly  formed by semi-conservative replication of DNA molecule of a single  chromosome.Thus they  are  like  </u><u>'photocopies' </u><u> of  original parent  chromosomes; joined together at the Centromere</u>.

They are exactly similar in all ramification; with the same gene and allele compositions..

<u>However; slight differences  arise between the two identical sisters due to  </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in  the  length of telomere repeats.</u>

Non-sister chromatids are dissimilar forms of  chromatids of a chromosomes formed  when each half of  a chromosome  at fertilisation from separate   haploid sex-cells, of each parent. fused.They contain different genetic composition;because  they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

<u>However, they are genetically  similar in composition; if they  are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by  chromosomal crossing-over between the non-sister chromatids  on the chromosomes ; therefore identical genetic characteristics are shared .
