So Mendel got roughly 75% yellow and 25% green in f2. This means that f1 contains all heterozygous genes, as shown below
Y y
Y YY Yy
y Yy yy
Summary: 75% YY or Yy, 25% yy
Which means that green (y) is a recessive phenotype, while yellow (Y) is a dominant phenotype, since plants with heterozygous genotype Yy express the yellow trait.
False, that is a close answer and can be easily confused with the right answer which is "Centromere" it is the specialized region of the chromosome where two sister chromatids are most closely attached.
The centrosome is like the organization center in the process of cell division. Has two centrioles.
