I Need Help With These Science Questions!!!Now!!?

Question

11) Explain how both genes and the environment determine how tall a person will be.

16) Explian why traits controlled by recessive alleles on the X chromosomeare more common in males than in females.

17) How is the sickle-cell disease inherited?

25) Explain how a horse breeder might use selective breeding to producehorses that have golden coats.

37) DEscribe how gene therapy might be used in the future to treat a person with hemophilia.

Answer 1

First of all, what a rude way to ask a question! The only thing I will tell you is that while one person was nice enough to help, they gave you bad information. A female has chromosomes XX and a male has XY. For #16, males exhibit these traits because they only have one X chromosome. Females have 2, so if one X has the recessive allele, the other X (if it does not have that allele) will shadow it.

Now, start reading and finish the other questions...they are straight from your textbook.

Answer 2

11) Your genetical information might say that you will be 6 foot tall, but if there are not enough nutrients and sources, it will be very hard for you to achieve the height that your genes carry.
16) because males have 2 Xs, and females only have 1X and one Y
17) sorry, i dont know
25) it depends if the golden coat is carried by a recesive or a dominant allele
37)

Answer 3

sickle cell disease is an example of incomplete dominance. people with homozygous dominant genotype HbA HbB form normal hemoglobin; those with the homozygous recessive genotype HbS HbS have sickle-cell disease and severe anemia. people with 2 sickle cell genes have severe anemia, and those with only 1 defective gene have minor problems.

Answer 4

Ha Ha, you should have done your homework over the weekend instead of partying it up.

Answer 5

You need to read your assignments!!! NOW!!! Then... THINK!
