Offspring

For the past decade technology has been advancing rapidly, so quickly that we have to stop and ask ourselves, should we genetically engineer our offspring? There are many different opinions on whether or not people should or should not be engineering their offspring’s, although the results could be devastating, some people still think it is a good idea. There are many pros and cons to this processes results. Some people might think it is a better thing because then they can have the perfect…

Sexual reproduction is a type of reproduction in which two different cells combine, which create an offspring. When two cells called the egg for female, and sperm for male, combine and join together they create a new organism called a zygote. During meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis has two divisions of the cytoplasm and the nucleus, the divisions are called Meiosis I and Meiosis II. Reproductive cells go through interphase before meiosis. “ A…

“Who made what?” After learning the different variations of genetic traits passed down to the offspring, my team and I were influenced to conduct research regarding the genetic variations of fruit flies. “Which mode of inheritance do the yellow body and curly wing trait follow?” After coordinating research, it is evident that: Because only 2 yellow bodies can only reproduce other yellow bodies, Curly wings can have either Curly or Wild-wing off spring, and the characteristics of dominant and…

Marion Petrie began her controlled breeding experiment with peacock offspring by observing peahen mate preferences in Whipsnade Park, UK. Observations showed that peahens appeared to have a preference for peacocks with more elaborate trains (i.e. larger in size and more eyespots). Petrie was interested in finding out why the peahens were mostly attracted to the peacocks with the most elaborate trains in this population. To test this idea, Petrie took eight males of different attractiveness from…

Bateman’s theory in respect of their ability to explain human mate selection. Darwin said, for the intent of surviving every species reproduce, whether they stay or leave after the offspring is born. Naturally males can reproduce more offspring than females as they are limited by the time, the carry their offspring which is for about nine months whereas, males just need a fertile female in order to reproduce. Brown, Laland and Mulder (2009). Many people have ideas on how males and females…

plants follow certain patterns. Like all experiments Mendel had to have a hypothesis, the experiment and the results. Gregor Mendel experimented with genetics to understand why offspring look the way they did. He started his experiments using pea plants because they are commonly and easily grown, they also produce a lot of offspring. Pea plants have a set of genetics that remain unchanged from generation to generation. Mendel wanted to see if he could change that. He also wanted to…

different positions in the nest, then there are two ideal sites, which cuts the offspring profitability in half. If both parents chose to sit in two locations relatively…

Some genetic mutations that occur during Meiosis or replication are not passed genetically to offspring. Though there are some genetic disorders that occur during replication or Meiosis that are passed onto offspring not all are. Some non-inheritable disorders are due to random events that occur in reproductive cells. An example of an event in a reproductive cell is the gain or loss of chromosome. All changes in somatic cells however are never heritable. Angelman syndrome is a genetic mutation…

output, forcing males to conversely share their reproductive output with the polyandrous female with the other members of the harem. In turn, males provide all the parental care for the clutch deposited onto the nest whether the clutch or individual offspring are “his.” This leaves all “good” thus reproductively successful descendants (Alcock 2010). A similar example is seen in Stephen Emlem’s (1998) work on polyandry in species the Wattled Jacana (Jacana jacana) one in which female jacanas…

The offspring look like their parents because each parent gives them half of their genetic material to their children. Coupled with, the Punnett square. The Punnett square helps determine the genetic genes a child may have from their parents. In this case, both offsprings can drink milk because their mom has a dominant trait. This allows her to overpower the dad recessive trait, allowing the offspring to drink milk. We focused on Punnett squares, dominate and recessive traits in two worksheets,”…
