ill start: Question 1 a) Centromer b) centromere splits as spindles contract pulling chromatids to opposite poles, producing 2 identical cells. c) different alleles d) chromosomes not replicated into sister chromatids as figure 2 is prior to synthesis. ( I put only contains sister chromatids idk) e) 3 chromosomes- 1 from each homologus pair( ie. one long,1 medium and one short)
Question 2 a)similar organisms capable of breeding to produce fertile offspring belong to the same gene pool b) groups withing larger groups with no overlap c) groups based on evolutionary relationships d)cant remember
ill start: Question 1 a) Centromer b) joins to spindle fibers in metaphase c) different alleles d) chromosomes not replicated into sister chromatids as figure 2 is prior to synthesis. e) 3 chromosomes- 1 from each homologus pair( ie. one long,1 medium and one short)
Question 2 a)similar organisms capable of breeding to produce fertile offspring b) groups withing larger groups with no overlap c) groups based on evolutionary relationships d)cant remember
some one please quote me and continue...
on 1 there was crossing over of chromatids as the final part

2d was species diversity increasing question,
Greater number of habitats/ niches Greater variety of food sources Greater number of species, and number of individuals survive
