Question

Help please- im still gonna keep wasting my points until someone helps i only have these 4 questions left man-

Answer 1

17. In Gregor Mendel's first experiment, he created a plant with purple flowers (PP , two dominant traits) with a plant with white flowers (pp , two recessive traits). What were the results of his experiment:

$\left[\begin{array}{ccc}&P&P\\p&Pp&Pp\\p&Pp&Pp\end{array}\right]$

a. 100% purple is your answer. Note that if there is a dominant trait, the dominant trait will show. In this case, purple is the dominant trait P, and is located on all quadrants, therefore 100% purple is your answer.

18. In Mendel's second experiment, he uses two purple flowers (Pp , one dominant, one recessive, each respectively). What were the result of his experiment:

$\left[\begin{array}{ccc}&P&p\\P&PP&Pp\\p&Pp&pp\end{array}\right]$

d. 75% purple, 25% white is your answer. The dominant trait P is found in three quadrants, with only the bottom right quadrant having two recessive trait p. This means that the quadrant with pp is white, and the others are purple.

19. Note that the Bob's dimples (DD) are the dominant trait, while Janet has the recessive traits (dd). Set the Punnett Square:

$\left[\begin{array}{ccc}&D&D\\d&Dd&Dd\\d&Dd&Dd\end{array}\right]$

d. 100%. In this case, the dominant trait shows up in all 4 quadrants, and will therefore mean that their child will have dimples. However, they will carry the recessive trait.

20. Matt and Meredith both have dominant brown eyes, but their daughter has blue eyes. This means that they both are carriers of a recessive blue strand (denoted by b.) This means that both Matt and Meredith are Bb. Set the Punnett Square:

$\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right]$

B) is your answer.
