Please help me solve these questions, Thank you!

question:
What are the chances that two individuals heterozygous for widow’s peak and free earlobes, EeWw, will have a girl with a straight hairline and attached earlobes (do not forget that gender outcome is also a probability)? (use Punnett Square)

In humans, Rh+ blood is dominant to Rh–. A man and woman are both Rh+, but their first child is Rh–.
Question:
What is the chance that their next child will be Rh–?

Question 19 options:

3/16


1/2


1/1


1/4

Some dogs bark while others are silent when trailing prey. The barking characteristic is due to a dominant gene (B). Erect ears (E) are dominant to drooping ears (e).
Question:
a.   
If you crossed a dog heterozygous for both traits with a droopy-eared, silent trailer, what are the chances that one of their offspring will be dominant for both traits (erect-eared, barking trailer)? (show Punnett Square)
