garden squash plants produce white or yelloe squash. White color is dominant while yellow is recessice. A squash plant that is homozygous for white is crossed with a homozygous yellow one. Predict the phenotype of the F1 generation (first generation) and the f2 generation (F1*F1)

Use the following genotypes to answer the question. N= big nose n= small nose B= big nostril b= small nostrl H= hairy face h= no hairy face XY= man XX= woman Z= zits on the nose z= no zits on the nose If two parents who are heterozygous for all the traits were 'crossed'...

Draw the structure of the product formed by the reaction between methyl alcohol and formic acid and give the molecular formula? I did not understand the answer that you gave me it did not make sense to me and I couldnt find it to respond back im sorry. If you wouldnt mind can ...

Draw the structure of the product formed by the reaction between methyl alcohol and formic acid and give the molecular formula HCOOH + HOCH3 ==> HCOOCH3 + H2O determine this molar concentration 58g of lithium in 54-ml of water molarity = mols/L mols Li = 58/atomic mass Li=?...

I am still not understanding this one at all. Draw the structure of the reaction product of 2-methyl-1pentene with H2 in the presence of platinum catalyst. This is the exact question it does not say cis or trans. I didn't follow DrBob222's reply, but I thought I had mi...

Hope you dont mind I have 3 more that I dont understand 1)Draw the structure of the reaction product of 2-methyl-1pentene with H2 in the presence od platinum catalyst 2)Draw the structure of 4-methylcyclohexanol 3)Draw the structure of 2,3-dibromotoluene 1)Draw the structure o...

I am totally lost on this one. 1,2,2-trimethylcyclopentane I think I have to draw the cyclopentane shape with the single bond going straight CH3 and I am lost from there. Draw the cyclopentane as a 5-cornered box. C-C | | C C \ / C Start numbering...

Is this the correct structure for cis-3-octene? CH3-CH2 CH2-CH2-CH2-CH3 \ / C=C / \ H H I can't tell what you have since we can't do spacing on the computer. But I think I can draw it like this: CH3-CH2-C=C-CH2CH2CH2CH3 Now stick a H atom to the #3 and one to the #4 C ...
