![]() ![]() Solid green leaves (G) are dominant to leaves with a white tip (gg). Tall corn plants (T) are dominant to dwarf plants (tt). Pea plants have genetics different from other organisms. He studied a trait that had a strange inheritance pattern. He decided to only look at his results in an objective manner. He studied the parental plants to determine their differences. He examined and analyzed both the F1 and F2 generations. Gregor Mendel was successful in his analysis of the genetics of pea plants because If you view a cell in which the genetic material is beginning to be visible as separate bodies, and the nucleus has disappeared from view, you may surmise that the cells is in What structure holds the sister chromatids to the spindle fibers? The genetic makeup of a particular trait in an individual is its What is the probability that a son with Duchenne MD inherited this disease from his biological father? ![]() ![]() With dominant genetic disorders, the mother and/or father of an affected individual must also be affected.ĭuchenne muscular dystrophy (MD) is inherited from an X-linked recessive allele. In recessive genetic disorders, the mother and/or father of an affected individual must also be affected. In carriers, the recessive allele causes an intermediate phenotype. With recessive genetic disorders, if both parents are carriers, the offspring will all be affected. The dominant allele is masked in homozygous dominant individuals. Which of the following statements is true: Sickle cell anemia is an example of what type of inheritance? The contractile protein, actin, is important only in plant cells.Ī contractile ring forms only in plant cells. In plant cells, the cell plate must also divide into two parts. Were the only traits seen in the F2 generation of pea plants in his experiments.Ĭytokinesis in plant cells differs from cytokinesis in animal cells because Were absent in the F1 generation of pea plants that he used in his experiments. If an organismâs diploid chromosome number is 18, how many different possible combinations of homologous chromosomes lining up during meiosis exist for the eggs or sperm produced by that organism?Īt the end of metaphase I, _ separate.Īre seen in all of the F1 hybrid pea plants in his experiments. ![]()
