Question 6

If there are two black guniea (BB, Bb) pigs and 1 white guniea pig (bb) what is the PROBABILITY the offspring will be black, or white. Explain

Answer 6

The answer is 50%

The punnet square would be
B b
b Bb bb
b Bb bb

Question 7

suppose one parent is (bb, yellow) and another is (BB, or Bb, black) draw a punnet square to determine what the offspring will be. what is the probability offspring will be black/yellow.

Answer 7

There is two ways to do the problems:

   B        B               B    b  b   Bb      Bb        b  Bb   bb  b  Bb      Bb         b  Bb    bb 100% black        50% or 1/2  dominant            has equalaity     takes over           in Bb & bb

Question 8

Which of the following is heterozygous ( heterozygous is lowercase)

aA

Answer 8
