Question

In gunia pigs, a rough coat R is the dominate over a smooth coat r .A particulare rogh-coated male genui pig?

is crossedwith asmooth coated female pig.use a punnett square to predict the genotype and the phenotype of therir off spring.hint;this is two pare problem.

i need help u guys

Answer 1

From what I remeber, it should be something like this;

For a rough haired male, genotype Rr-

Upper left of square: Rr

Upper right: rr

Bottom left: rr

Bottom right: rr

For rough haired male, genotype RR-

Upper left: Rr

Upper right: Rr

Bottom left: Rr

Bottom right: Rr

Depending on the males gene for rough coat, RR or Rr, you've either got a 75% chance of a smooth coat offspring or a 0% chance.  It's really hard to tell without knowing the father's exact code.

Hope this helps
