Amale carrier of a recessive somatic mutation marries a female without this mutation. what is the probability that their child will be a carrier? a. 0% b. 25% c. 50% d. 100%

The correct answer is C. 50 %

A male is a carrier of a recessive somatic mutation it means the mutation can be expressed under homozygous condition, when both the alleles with somatic mutation. Thus, in case of a male carrier of a recessive somatic mutation marries to a normal female will produce 50 % their offspring with recessive somatic mutation so, they will be carrier and 50 % offspring are without this mutation.

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
