Meeting this challenging task requires an understanding of the meaning of empathy, the use of diverse educational techniques, and incorporation of students' personal experiences. Acknowledging the role of empathy is easy, but teaching empathy is difficult because empathy is an elusive idea.
The sister chromatids are connected to each other at a point called the centromere. During mitosis, the nuclear envelope dissolves, and sister chromatids separate at the centromere, becoming two individual daughter chromosomes, each now with only one chromatid.
The homologous chromosomes separate during meiosis 1.This time, the MI results in two cells, each containing both alleles (1 tan, 1 wild type). Meiosis II (MII) results in separation (segregation) of the two alleles for spore color.A mitotic division results in eight spores arranged in the 2:2:2:2 or 2:4:2 pattern. Anyone of these spore arrangements would indicate that crossing over has occurred betweenthe gene for spore coat color and the centromere.
