what are 3D base pairs ?
Answer / biomaster
Each DNA molecule is made up of two spirally coiled chains
made up of sugars and phosphorus molecules and in the
middle nitrogenbases.This arrangement looks like a ladder.
nitrogen bases are adenine, guanine, thiamine, cytosine.
Adenine always pairs with thiamine by two hydrogen bonds.
These are known as 2D base pairs.
Guanine always pairs with cytosine by three hydrogen
bonds.These are known as 3D base pairs.

In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino?
How is an allele different from a gene?
For each of the following, state whether it is a gamete or a genotype of an individual a) TT b) Tg c) IcCC d) TW
A normally pigmented man (dominant) marries an albino woman (recessive). They have 3 children, one of whom is an albino. What is the genotype of the man?

Can you name a few potential risks of Genetic Engineering?
Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
what are the sex linked traits in humanbeings?
Different between back cross and test cross
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
