Im doing a bio project on Mendel. I need to know how his f1 generation plants differ from his f2 generation plants. any ideas? ||| pure race: AA (yellow), aa(green)
A dominant fenotipe
a recesive fenotipe
parents P............AA....x.....aa
generation F1.............Aa (the one half of each from parents)
generation F2 .......Aa x Aa
--------------------------------------鈥?br>
.............1/2A............1/2a...
--------------------------------------鈥?br>
1/2A..... 14AA...........1/4Aa
1/2a......1/4aA...........1/4aa
--------------------------------------鈥?br>
Result: 1/4 Aa + 1/4 Aa + 1/4aA = 3/4 yellow
.............1/4aa= 1/4 green
Rate.....3:1
In the first generation (F1), all the descendant are yellow (dominant fenotipe A). Its genotipe is Aa
In the second generation (F2) appears the recesive fenotipe a, so the rate is 3 yellows and 1 green. Its genotipe is Aa aA AA aa. It is said, in the second generation the pure races AA aa appear again while in the first generation it is a hybride in which the fenotipe a (green) didn't appear (recesive)
