50 points and brainleist how can i gain weight if i was born 4 days early than due date DON'T GOOGLE
ivann1987 [24]
Being born a few days before your due date shouldn’t cause a big difference in your health. To gain weight you should try to eat thing high in protein, healthy fats, and some carbs. Most people try to gain weight by eating foods with a lot of saturated fat (is potato chips) but try to maintain a diet with a good calorie intake.

However I am not a professional and if you are worried about your weight, go to a nutritional to see what meal plan they will give you

This is what I try to eat, I am 100 pounds, 5.2, female.
Eggs (taste terrible in my opinion but are extremely nutritious) for breakfast
Salad with chicken for one meal
Meat dish with rice, or vegetables, sometimes spaghetti

Self cross in F2:

offspring by Punnet cross are:

RRCC  -->1/16  

RRCc,  RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes
