Artificial cross-fertilization - Answer- removing anthers from a flower and introducing pollen of the desired type with a small brush Pure-breeding strains - Answer- strains that consistently produce the same phenotype Took Mendel two years to prepare his P1 (Parental) generation - Answer- The original parents F1 (Filial) generation - Answer- offspring of the P generation Replicate crosses - Answer- repeat each cross several times Reciprocal crosses - Answer- The same genotypes...

A cleavage furrow is _____. A) the space that is created between two chromatids during anaphase B) a ring of vesicles forming a cell plate C) the separation of divided prokaryotes D) a groove in the plasma membrane between daughter nuclei E) none of the above - D) a groove in the plasma membrane between daughter nuclei Taxol is an anticancer drug extracted from the Pacific yew tree. In animal cells, Taxol disrupts microtubule formation. Surprisingly, this stops mitosis. Specifically,...
