A certain species of rabbit can have either black or grey fur. The allele for black over the grey fur. If a homozygous black rab

Scilla [17]

Answer:

100% black

Explanation:

<em>The allele for black is dominant over that of the grey fur.</em>

Let B represents the allele for black color and b for grey color.

Homozozygous black rabbit will have the genotype: BB

Heterozygous black rabbit will have the genotype: Bb

If the two are crossed;

BB x Bb

Offspring: BB, Bb, BB, and Bb = 2BB and 2Bb

2BB = Black fur

2Bb = Black fur (heterozygous)

Both BB and Bb offspring are black phenotypically.

<em>Hence, all the offspring will appear black, a phenotypical ratio of </em><em>100% black.</em>

The units used by the biomass pyramid are individual units. Because the biomass pyramid calculates mass and sequences from each individual living creature ranging from large to small such as whales, elephants, cats. chicken, rat, ant, to bacteria.

<h2>Further explanation </h2>

The biomass pyramid illustrates the total weight of organisms that occupy each trophic level. To measure biomass at each trophic level, the average weight of organisms at each level is measured then the number of organisms at each level is estimated.

In ecology, biomass is the mass of biological organisms living in an area or ecosystem at a certain time. Biomass in ecology can refer to the biomass of species, which is the mass of one or more species, or community biomass which is the mass of all species in a community.

Biomass is grouped into four groups:
