D1- Analyse the Significance of Genetic Influences as Opposed to Social Factors in Human Development

Most brothers and sisters don’t look exactly the same. What causes most siblings to have different

Twins, share a bond that no parent, child or sibling relationship can ever compare. There are two main types of twins, and these include: monozygotic (identical) twins and dizygotic (fraternal) twins, and they are compared by their emotional, behavioural, and cognitive similarities. (Robert Plomin, 1997). According to Social Issues Referencing, 2007, whereas Identical twins are formed from a single (mono) zygote and are genetic “carbon copies”, fraternal twins develop from two (di) separate zygotes, as a result of two eggs being fertilized by two sperms independently. (Social Issues Referencing, 2007, para. 8)

The historical debate regarding nature and nurture has been going on for years and is still unresolved. Many theorists believe what we have inherited and our genes, makes us the way we are and how we develop. Other theorists believe it is the way we are brought up and our experiences, that make us the way we are and how we develop.

Although they are boy and girl twins at first no one believes that they can be identical, although rare, it is possible. The two share every possible feature; their jet black tight curls that flop atop their heads, hazel eyes that sparkle when they smile and skin so chocolate you would think thy were manufactured at Hershey.

Chapter Four discusses, similarities and dissimilarities of twins, Rainbow the cat and her clone Cc aka "Carbon copy" have exactly the same DNA. GxE will guarantee a difference between the two cats. Cc was white and gray compared to Rainbow she was brown, tan, white and gold, Cc was curious and playful, as Rainbow was quiet and calm. Even though Cc and rainbow shared exactly the same DNA these two cats were distinctly different from each other. In 1979, southern Ohio Jim Lewis tracked down his long lost identical twin Jim Springer, When Jim meet Jim, it was if he was looking in a mirror. Both men discussed their life, to find that they had distinct similarities in the way they

Twins are together from the moment they are born, so they learn everything about each other. I was actually told that Lillie and I had a secret language and we told one another to do things without ever having to let anyone else know (which was impossible since we couldn’t talk). Therefore, as twins are super close, we’d both probably just know which color the other one would pick based off of what the other one likes.

It must be mentioned that neither of the twins might be the same skin color as their genes code for because both twins are impacted by their unique environments. In a developmental system scientist’s point of view, the environment has a direct impact on how a phenotype is expressed. The differences that identical twins have tend to get greater as they get older. For the most part as twins get older, they become more independent and experience much more varying environments. Therefore, the twins differing environments will cause different phenotypes to be expressed.

Most siblings have a lot of things in similarity such as their appearances, their style in music and fashion, and their lifestyle. However, Justine and Jacklyn are very different from each other when they are brought together. Many people will see these two as just people who look the same, who act the same, and who live the same way, but there is so much more to that then just being “the same person”. Appearances ARE everything. Justine and Jacklyn are fraternal twins which means that they do not look alike

Nature is genetics, and it helps shapes personality. Like Anais and Sam, they have a lot of the same things. They both like the same pop have the same laff, and there both outgoing.They also had the same pet peeves.The Jim Twins have the same personality, they love to woodwork and the same beer.They both had wives named Bettie and Linda. They also had the same son name Jams, Allan.The twins Jack and Oscar had the same jacket and glasses on when they met.Both of them were competitive and they passed away from cancer. When they both met they were really emotional. MISSING EVIDENCE

From the movie of Baby Genius, we have an idea that twin babies have their similarity or differences between their own characteristic. They develop their own individual personalities to enable themselves to be recognised as individual persons. Twins are unique individuals that create their own individual likes and dislikes. They usually noticeable marks of differences when identical twins are observed separately or together. Therefore, we create our topic of this project named as The Uniqueness of Single Zygote Baby.

Nature is your genetics in how your personality is gonna be.Sam and Anal are twins who were born together but separated at birth. They were reunited when they were 20. They were interviewed and when they would laugh they had the same laugh. They both had the same pet peeve of a shower curtain touching them while showering. They both liked the same things and they both liked art. There are also other twins like Sam and Anal the Jim twins. The Jim twins were separated at birth like Sam and Anal. The Jim twins were alike in many ways. They both liked woodworking. The Jim twins first wife's names were Linda. Both of their second wife's names were Betty, and their third wives names were Sandy. They named their first kids the same name James. They both smoked the same cigarettes. There was also another pair of twins. Their names were Bonnie and Brenda. Bonnie and Brenda did everything together when they were little. But as they grew up Brenda notices Bonnie was a little bit different from the other girls. Bonnie was different because she liked girls. Brenda then felt their relationship between each other was ruined. Then when Bonnie said she wanted to change genders and she did. Brenda was ruined she never looked at her sister the same. A

Nature is genetics that comes when you are born. Nurture is the environment, it is how you act, and your personality. Scientist have researched identical twin that were separated at birth. The twins names were Daphne and Barbara! They had a lot in common even though they didn't live together or even know eachother. For examples, they both dropped out of school at the age of 14, then they both fell in love at 16 . They also both had miscarriages at the same age! Next scientist research on the Jim twins. They were also separated at birt. They happened to be named the same thing! They had a lot in common also, like they had 3 wives, and they were all named the same. They also named their first child the same name. Last but not least, Jack and Oscar. They also had a lot in common too but in a different way, like they didn’t like that they had so much in common, they also didn’t like how they wore the same thing as each other. From all that information I believe that nature is more important, because they were all separated at birth, they still have the same feel and taste, because it was in there genetics. They all might have been raised different, but after all they have the same things.

Nature vs. nurture has been a major debate throughout the ages, it I one of psychology’s oldest debates. Nature is what you were born with, and nurture is how you are raised. There are obvious traits that you obtain from DNA such as, eye colour, hair colour, and the pigmentation of one’s skin. But how can you tell whether or not one’s personality is inherited or acquired has been a major question. Or even is one’s sexuality is inherited or acquired. Some aspects of life are determined by nature and others are determined by nurture. There are many different aspects of life that depend on nurture, and there are others that depend on nature. There are even unexplained human behaviour such as twin studies, and unethical experiments such as ‘Edith

The similarities of genetics in siblings can have a strong effect on how you grow up. Even though they are not twins. Two sisters named, Margie and Melissa are similar in many ways. Not only do Margie and Melissa share the same birthday. They were born in the same hospital, 19 years apart. Which can be a sheer coincidence and have nothing to do with genetics. However, because of genetic similarities the sister’s physical features are incredibly similar. Both sisters are petite in size with the same exact height. Also, both sisters have the same slanted eye shape that they inherited from their mom. On the other hand, there are genes that siblings inherit from their parents that can be extremely strong. Not only can their genes effect their

hich I believe makes it an insignificant implication in comparison to the possible outcomes of PGD, which is the high percentage of having a healthy child which to many definitely outweighs the risk of biological implications such as OHSS.
