48. For a dihybrid cross between two heterozygotes-what is the probability of producing an offspring that displays both dominant traits?
a. 1/16
b. 3/16
c. 9/16
d. 3/4
49. For meiosis and mitosis which of the following is a correct statement?
a. Meiosis results in the production of 2 new identical cells and mitosis results in the production of haploid cells that are not identical.
b. Mitosis results in the production of 2 new identical cells and mitosis results in the production of haploid cells that are not identical.
c. The end result of both processes is that 4 new haploid.
d. The end result of both processes is that 2 new haploid.
50. The scientific method begins with ______.
A. Experimentation
B. A hypothesis
C. A conclusion
D. an observation
Solution
48. c. the probability of producing a hybrid with both the dominant traits is 9 out of 16.
49. b. Mitosis is the division by which cells multiply. A cell divides to form two daughter cells which have the same amount of chromosomes and other cellular components. On the contrary in meiosis there are four daughter cells formed which are haploid and their genetic material is not identical.
50. d. The scientific method begins when you ask a question about something that you observe.
