Northern foxes have black fur as the dominant trait, while red fur as the recessive trait. The genotype for the fur color of northern foxes is given below.
Identify the phenotype for each of the following:
BB: bB: bb: Bb:

BB indicates that the gene is homozygous dominant.

bB: indicates that the gene is heterozygous dominant.

bb: represents that the gene is homozygous recessive.

Bb: shows that the gene is heterozygous dominant.

Explanation:

Capital alphabet is used to describe dominant allele while small alphabet is used to show recessive allel. If both allele are small or capital alphabets so it is homozygous while if both allele are different so it is heterozygous gene.

Northern foxes have black fur as the dominant trait, while red fur as the recessive trait. The genotype for the fur color of northern foxes is given below.

Identify the phenotype for each of the following:

BB: Black fur dominant homozygous

bB: Black fur dominant heterozygous

bb: red fur recessive homozygous

Bb: Black fur dominant heterozygous

Explanation:

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
