Frederick Griffith accidentally discovered transformation when attempting to develop a vaccine for pneumonia. He injected mice with samples from S-strain (virulent) and/or R-strain (non-virulent) pneumococci bacteria (Streptococcus pneumonia). Which of the following results is not consistent with Griffith's experiments?
a. injected R-strain; mouse lives.
b. injected S-strain; mouse dies.
c. injected heat-killed S-strain; mouse lives.
d. injected mixture of heat-killed S-strain and live R-strain; mouse lives.
e. injected mixture of heat-killed R-strain and live S-strain; mouse dies.
A mainland population of 10,000 ground beetles have the neutral alleles A1 and A2 with frequencies of A1 = 0.4 and A2 = 0.6. 16 male and 20 female beetles found a new population on Russell Island.

Whether it was volcanic activity that spewed sulfur dioxide and ash into the atmosphere, or a giant meteor that crashed into the Earth blasting dust and debris into the sky.
What methods would you use to determine if the genes had been co-transduced in the recipient cell?
The rule of independent assortment states that alleles of one gene can segregate independently of alleles of other genes. In other words, the allele you pass on for one trait (for example, eye color) does not have any effect on the allele you pass..
