The figure above shows a metaphase in which one chromosome is only connected to the spindle by a single kinetochore, thus the sister chromatids may not separate correctly during anaphase. which of the following statement/s is/are correct;
Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.
