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

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
