What is an example of Homologous chromosome?
x chromsones/y chromosomes
How many chromosomes has a human?
Chromosomes contain the DNA of many characteristics that humans may have - gender, hair color, eye color, skin color, etc. Humans have forty-six chromosomes. Chromosomes are often paired together - humans have twenty-three chromosome pairs. 46; 23 from each of my parents. ---- Humans have 22 pairs of somatic chromosomes and 1 pair of sex chromosomes, for a total of 23 pairs. Female have two X sex chromosomes and males have one X and one Y sex chromosome.
The genes on the x and y chromosomes are called what?
The genes carried on the X and Y chromosomes are called your "sex chromosomes".
Chromosomes other than X and Y?
Chromosomes that are not X or Y are called homologous chromosomes and autosomal chromosomes. The first 22 pairs of human chromosomes are autosomal.
What is true about a baby with two X chromosomes?
A baby with two X chromosomes is female.
What is an example of Homologous chromosome?
x chromsones/y chromosomes
5 Explain why there were no white eyed female fruit flies?
The gene for eye color is only carried on the X chromosome. Since females have two X chromosomes and white is recessive, there are no white-eye females.
Why are some traits passed from parent to offspring?
Why? Because you can't be just a nothing, you have to have something in common with parents and you can't have a plain face! If you get two x chromosomes you will be a girl but if you get one y chromosome, you end up being a boy. Either way you will have two chromosomes and one of them will be an x.
What alleles cause color blindness?
carried on the X chromosomes
What is the location of the eye color of a fruit fly meaning which chromosome?
The locus for eye color is on the X chromosome.
How do you get the disease of color blindness?
You do not get color blindness, you are either born with it or not born with it. It is on the X chromosome. A male has one X chromosome. A woman has 2 X chromosomes. If one X chromosome does not have red-green capability and the man has that chromosome, then he is color blind. A woman can have one color blind chromosome and one non-color blind chromosome and she will not be color blind. The ability to see blue and yellow is on chromosome number 7. Everyone has two of those. A man can only have 3 color chromosomes. Women can have 4 color chromosomes. Since the chromosomes can be slightly different, women can frequently see far more color variations than men can see.

What sex chromosomes do females produce in their egg cells?
X chromosomes (X,X)
Red-green color blindness is a human genetic disorder cause by?
Color blindness is a sex-linked genetic disorder. The reason that it is more prevalent in males is because the disorder is linked the the X-chromasome. If a male inherits an X chromosome that is defective, then they will be color blind. However, a female has two X chromosomes which means she can receive a defective chromosome and only be a carrier of the mutation. If she receives two defective x chromosomes, she will be colorblind.
What are the X and Y chromosomes called?
The X and Y chromosomes are called the "Sex Chromosomes". Both the X and Y chromosome are part of the "sex-determining system" that helps determine the sex characteristics in humans. In the system, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).
