Answer 1

QUESTION 29 and 30 Rr x Rr IR RR Rr R Ir Rr r r 2/3 = Red (Rr) 1/3 = Black (rr) So, the correct answer for question 29 is 2/3 and for question 30 is 1/3 QUESTION 31 and 32 Rr x Rr R Rrrr Rr r r r. Ir 2/4 = 72 = Red (Rr) 2/4 = 1/2 Black (rr) So, the correct answer for question 31 is 1/2 and for question 32 is 1/2 Note: According to Chegg's guidelines, you have to send just one question.
