How can the random distribution of alleles result in a predictable ratio?
levacccp [35]
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>

Basic concepts of carbohydrates and it's importance?​
natulia [17]
-carbohydrates contain carbon , hydrogen and oxygen
-also known as saccharides
-glucose is a hexose monosaccharide (composed of 6 carbons )
-two structural variations: alpha α and beta β glucose ,in which the OH group on carbon 1 is in opposite positions
- glucose : polar and soluble in water due to the bonds that form between the hydroxyl groups and water molecules
-glycosidic bond : bond formed between two glucose molecules by a condensation reaction forming a disaccharide
-fructose +galactose =sucrose
-galactose +glucose = lactose
- starch :many alpha glucose molecules can be joined by glycosidic bonds to form two slightly different polysaccharides
- one of the polysaccharides of starch is called amylose
- amylose : formed by alpha glucose molecules joined together only by 1-4 glycosidic bonds
-amylopectin: both 1-4 and 1-6 (every 25 glucose subunits )glycosidic bonds between alpha glucose molecules. 1-6 glycosidic bonds cause branching
-glycogen : more branches than amylopectin . Compact so ideal for storage . Speeds up the process of storing and releasing glucose molecules required in the cell.Insoluble
-hydrolysis reactions opposite of condensation reaction
-cellulose:beta glucose molecules. Join together by alternate beta glucose molecules turn upside down
- straight chain molecule: cellulose
-cellulose molecules make H bonds with each-other forming microfibrils. Microfibrils join together to form macrofibrils which combine to produce fibres
