Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly
Explanation:
Lemon is more acidic, it has a pH value around 2.0
meanwhile, orange has a pH of around 3.0
watermelon is the least acidic, it has a pH value of around 9.0, which is an alkali.
Besides testing for the pH value with universal indicators, we can do simple taste test (only food!). usually the more sour a food is, the more acidic it is. lemon is the most sour food out of three, and it's the most acidic.
