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 .
Explanation:
In science a hypothesis is useful only if...
1: it could be tested
2: their are two separate group
3: it's supported by evidence and facts
Answer:
The correct option is<em> D. Tell the surgeon that the brother-in-law will decide after explanation of the proposed surgery is provided to him and the widow</em>
Explanation:
In the Sub- Saharan region, the customary law allows the inheritance of wife and the culture of having more than one wife is also practised in this region. According to the law, the widow will become the inherited wife of her deceased husband's brother.
In those regions, the woman are suppressed and the regions are male dominant regions. The women have to obey men's command. Hence, it will more likely be that the brother- in- law will make the decision.
