Dihybrid cross Study guides, Class notes & Summaries

CHECKPOINT 12 Genes located close together on a chromosome tend to be inherited together. What is this called? correct answer: genetic linkage Which of the following genes are linked in pea plants? correct answer: flower color and pollen-grain shape A Punnett square incorrectly predicts the outcome of a dihybrid cross. There are only two phenotypes in the F2 offspring instead of four. Why? correct answer: The genes are completely linked. A Punnett square predicts that the ratio of ...

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.
