In a diploid set of chromosomes, one member of each pair of homologous chromosomes is derived from the father (paternal), and the other comes from the mother (maternal). If 2n = 6, what is the probability that a particular gamete will contain only paternal chromosomes?

Answers:

The options

A. 1/4

B. 1/8

C. 1/16

D. 1/32

E. The answer cannot be determined

The CORRECT ANSWER IS B

B. 1/8

Explanation:

The probability of a singular paternal chromosome been found in a specific gamete = 1/2

Therefore, the probability that all the three would have a paternal source = (1/2)^n

Where,

n = 3

(1/2)^3

= 1/8

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

0 because theres a difference between pickled peppers and peers.
