My sister and I are very similar in both looks and personality.� We're only 18 months apart in age and people ask us all the time if we're twins.� We're not really identical, but not all twins look exactly the same.� Lexy, that's my sister, isn't quite as tall as I am and her hair is more wavy than curly like mine, but besides that we have pretty much everything else in common.� There is one big difference though - she has brown eyes and mine are blue.�
One morning, Lexy asked me why she didn't have blue eyes too.� �I told her it was because our mom has brown eyes, but when I actually thought about it, I realized I wasn't really sure how it all worked.� We went to find our blue-eyed dad to see if he could explain things a little better.�
When we found

I flipped through a book on genes with Miss Rachel and found out that we currently know of three genes that impact eye color.� These genes are located on chromosomes you inherit from both your mother and father.�
"I still don't understand how our eyes could turn out different," Lexy complained.� She was starting to get bored with our little research project.
"Hmm," said Miss Rachel.� "Let's see if we can find something online that might illustrate the concepts a little more clearly."
She led us to a computer terminal and helped us generate a list of keywords to search.
chart����������� The first site we landed on showed us an illustration of the two genes that scientists know the most about when it comes to inherited eye color: bey2 and gey.� It said that each of the genes have two forms called alleles.� The bey2 gene has brown and blue alleles and the gey gene has green and blue alleles.� Your eye color depends on the combination of alleles you
Identical twins look so similar because identical twins have the same genetic makeup, meaning, the same DNA (same nitrogenous bases). This is because by they are fertilized by the same egg, making them identical.
Most twins also have a few close friends that are separate from their sibling. Most don’t share a personality. Again, some small parts are the same, but these parts can be explained by environment. My sister and I have different interests, are involved in many different activities, and have aptitudes in many different things. For instance, she is involved very heavily in the theater and political science departments at her college, and I am involved in volunteer work wherever I can find it and the nursing department. Finally, we don’t usually dress alike. We have not dressed in the same outfits every day since the age of six, when we started helping pick out our own clothes. When we do dress alike, it is only for special events. For instance, we are planning to do so for three days at the end of summer, due to our attendance at the Twins Festival in Twinsburg, Ohio and most twins find this a fun way to celebrate being a twin. Most pairs have the same philosophy. They may dress up for holidays or birthdays (the parents and other relatives find it cute), but not on an everyday basis. There are, of course, exceptions to the rule. Some twins like to dress alike all the time, even as grownups. Some have the same friends, and some even have eerily similar personalities. To these people, I say “More
4. Clear wing, Black eye, and Hairless (c, b, and h) are linked, recessive traits carried on
Too black for the White kids, yet somehow too white for the Black kids, oh the perils of a cappuccino mixed race kid. But it’s true. My life since I was young, at least younger than my eighteen year old self, has been about which group do I most fit in with. Between the four school changes over the course of twelve years, all in white suburban towns I’ve molded myself into an array of characters.
The resemblance has shortly disappeared as I got older but we still have the same hair and face. My sister looks nothing like us but the only thing that she has in common with my brother and I is probably the eyes. My sister and I have weird moments where we both have the same exact idea or thought in our mind at the same exact moment. My brother, sister and I are all athletic. We love sports a lot. We all love sports because it’s fun and it keeps us healthy. I love sports because the feeling of competitism feels great when it courses through you. My brother and I have the same ego also. When we get tested by our athleticism, we want to prove it by playing the
It has been said that many siblings are very similar; However my sister and I are nothing alike we are actually very different. When two people have the same blood type and genotype is not insured that you will be exactly the same. Having same parents increases the chances of having the same genes though. All Siblings have various behaviors and personalities that make them dissimilar. Siblings have a genetic and physical closeness that connect them together. It is reasonable that not all sisters resemble each other. My sister and I are completely opposite.
If Aunt Muriel and Uncle Charles both have blue eyes, could their brand new baby have brown eyes?

Everyone in their life will face a barrier. A barrier is a challenge or obstacle that makes it difficult or prevents you from moving forward. Some examples of a barrier you would face would be a death in your family,drugs or alcohol,etc. My barrier that I faced was of the unknowing. My friends and family were all involved with my barrier. I have my barrier everywhere I go. I've been faced with my barrier for a ew years now.
Most genes don't do anything as flamboyant as the changing our eye color, instead, they make enzymes, which are deep inside our cells. These enzymes are important for organisms because they do different jobs that are needed for living, for example, running chemical reactions that are used help us digest our food, and burn energy. Metabolism is the name of these chemical reactions.
He saw the expression on her face go from confusion, to disbelieve, and then to realization in the matter of mere moments.
He watched her out of the corner of his eye. “What did you think of my summary?”
Before researchers were able to find a way to make this possible, they first had to understand more about genetics. Genetics explains the process of parents passing down genes to their children, these genes are things like hair colour, eye colour and genetic disorders. Every human has 23 pairs of chromosomes, 43 individual, and within them is where the genes are carried, each chromosome holds about 20,000 genes.
Colorblindness is the inability to distinguish the differences between certain colors. In order for a girl to have the genes for colorblindness the father must be colorblind. Women mostly carry the trait instead of fully expressing colorblindness. Since colorblindness is a recessive trait the mother must carry the trait and the father must be affected. In the image at the bottom of the page you can see that in generation four person seven is an affected female. Above that in generation three her parents are a carrier female and an affected male therefore, she gets the affects of colorblindness.
Introduction: The gene that codes for red-green color blindness, the most common form of color blindness in humans, is found on the X chromosome. One in 12 males is color blind. In females, however, color blindness affects only about 1 in 200. Why is
Based upon observation of the F1 generation, we hypothesize that the inheritance of the white-eye (W) mutation is sex-linked and recessive wild type.
