The yeast Saccharomyces cerevisiae divides by budding: instead of dividing to produce two identical daughter cells, the so-called mother cell buds to produce a daughter cell, The HO gene is expressed only in mother cells and only at a certain point in the cell cycle,

1. SBF	I- Which is active only during the G1-S transition of the cell cycle.
2. SWI5	II-Which acts only in the mother cell.
	III- Recruit nucleosome modifiers

in a rare blood type referred to as the bombay phenotype, individuals are unable to attach the a or b antigens to their red blood cells. individuals that are homozygous recessive for gene "h" have the bombay phenotype and their blood type is type "o" regardless of their abo genotype. this is an example of what extension of mendelian inheritance?
