Question

8. A slot machine has 10 slots. Each slot has 4 different fruits on the spinner (apple, pear, grape, and cherry). What are the odds of getting a cherry in BOTH the first AND second slot? a. 1/2 b. 1/4 c. 1/8 10 e. 1/4 You have 23 pairs of chromosomes in your somatic cells. Each homologous pair is comprised of one chromosome from your mother and one from your father. What are the chances of making a gamete (sperm cell or egg cell) in which all of the chromosomes are from your father? For this question, assume that there is no meiotic crossing-over a. 1/2 b. 1/214 c. 1/23 d. 1/246 e. 1/292

Explanation / Answer

8)here as 4 fruit on each slots ; therefore probability of a cherrry on a slot =1/4

hence P(both firsrt and second slot has cherry) =(1/4)*(1/4) =1/16

option d

9)here as for each pair thre are 2 choices and total type of possible gamete =223

there is only one way all chromosome is from father

hence probability =1/223

option C
