Problem: Most sexually reproducing organisms are diploid, with paired chromosomes, but doubling of their chromosome number may occur due to errors in cytokinesis. This can occur early in development to produce an autopolyploid or partly autopolyploid organism, or during normal processes of cellular differentiation to produce some cell types that are polyploid (endopolyploidy), or during gamete formation. An allopolyploid plant may result from a hybridisation event between two different species. Both autopolyploid and allopolyploid plants can often reproduce normally, but may be unable to cross-breed successfully with the parent population because there is a mismatch in chromosome numbers. These plants that are reproductively isolated from the parent species but live within the same geographical area, may be sufficiently successful to form a new species. Some otherwise sterile plant polyploids can still reproduce vegetatively or by seed apomixis, forming clonal populations of identical individuals. Durum wheat is a fertile tetraploid allopolyploid, while bread wheat is a fertile hexaploid. The commercial banana is an example of a sterile, seedless triploid hybrid. Common dandelion is a triploid that produces viable seeds by apomictic seed.
Can these plants cross breed with the parent population of plants?
The answer is the following: unable to cross-breed successfully

Problem: In the early 15th century, the countries of the Iberian peninsula began to sponsor exploration beyond the boundaries of Europe. Prince Henry the Navigator of Portugal (d. 1460) sent expeditions that discovered the Canary Islands, the Azores, and Cape Verde during his lifetime. After his death, exploration continued; Bartolomeu Dias (d. 1500) went around the Cape of Good Hope in 1486 and Vasco da Gama (d. 1524) sailed around Africa to India in 1498. The combined Spanish monarchies of Castile and Aragon sponsored the voyage of exploration by Christopher Columbus (d. 1506) in 1492 that discovered the Americas. The English crown under Henry VII sponsored the voyage of John Cabot (d. 1498) in 1497, which landed on Cape Breton Island.
What leader sponsored the expedition that discovered Cape Verde?
The answer is the following: Prince Henry the Navigator

Problem: Scholars have characterized To Kill a Mockingbird as both a Southern Gothic and coming-of-age or Bildungsroman novel. The grotesque and near-supernatural qualities of Boo Radley and his house, and the element of racial injustice involving Tom Robinson contribute to the aura of the Gothic in the novel. Lee used the term "Gothic" to describe the architecture of Maycomb's courthouse and in regard to Dill's exaggeratedly morbid performances as Boo Radley. Outsiders are also an important element of Southern Gothic texts and Scout and Jem's questions about the hierarchy in the town cause scholars to compare the novel to Catcher in the Rye and Adventures of Huckleberry Finn. Despite challenging the town's systems, Scout reveres Atticus as an authority above all others, because he believes that following one's conscience is the highest priority, even when the result is social ostracism. However, scholars debate about the Southern Gothic classification, noting that Boo Radley is in fact human, protective, and benevolent. Furthermore, in addressing themes such as alcoholism, incest, rape, and racial violence, Lee wrote about her small town realistically rather than melodramatically. She portrays the problems of individual characters as universal underlying issues in every society.
What genre of book is To Kill a Mockingbird typically called?
The answer is the following: Southern Gothic and coming-of-age or Bildungsroman novel

Problem: Genetic engineering is the modification of an organism's genome through biotechnology. Since the 1970s, a variety of techniques have been developed to specifically add, remove and edit genes in an organism. Recently developed genome engineering techniques use engineered nuclease enzymes to create targeted DNA repair in a chromosome to either disrupt or edit a gene when the break is repaired. The related term synthetic biology is sometimes used to refer to extensive genetic engineering of an organism.
What sort of DNA repair is created by modern genetic engineering techniques?
The answer is the following:
targeted
