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:
Answer:
Explained below
Explanation:
1) Olfactory nerves are responsible for our sense of smell while auditory nerves are responsible for our sense of hearing.
2) Olfactory nerves are the shortest nerves and are those that enter the skill through the cribform plate from the ethmoid zone while auditory nerves is one out of two parts of the vestibulocochleer which is described as a cranial nerve that's present in amniotes. The other part is the vestibular nerve.
Answer:
3 types I think
Explanation:
Continuous, Fragmented and absent.
I believe they will disappear from the area because they’ll either die from the disease in there food or migrate somewhere else for a different source of food
I think it’s a if I am not mistaken
