If T stands for tall pea plant and t stands for short pea plant, what is the phenotype of a pea plant with allele combinations Tt, TT and tt. You should have an answer for each combination.

Tt will be tall phenotypically, TT will be tall phenotypically, tt will be short phenotypically.

Explanation: From the information provided above, T stands for tall pea plant. This indicates that T is dominant because dominant alleles are written in upper cases. t stands for short pea plant. This indicates that t is recessive because recessive alleles are usually written in lower cases.

A dominant allele has the ability to express itself in the presence of a recessive allele, it masks the effect of a recessive allele. A dominant allele will express itself both in a homozygous and heterozygous state. A recessive allele do not have the ability to express itself in the presence of a dominant allele, its effect is masked by a dominant allele. A recessive allele can only express itself in a homozygous state.

Therefore, T will express itself as tall pea plant both in Tt and TT while t will express itself as short pea plant in tt.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
