A soil sample from a temperate deciduous forest would be more nutrient rich that a sample from the tropical rain forest.
In the rain forest the tree tops form a canopy and the tops of trees absorb 90% of the sunlight and only 10% can get down to the understory which is the area under the canopy. The soil is very nutrient poor.
In a temperate deciduous forest there is no canopy so more sunlight can get to the soil. Which makes it more nutrient.

Dominant alleles are the alleles that show that show the physical traits

42% of rabbits in the population are heterozygous for the mutant Sp1 allele
Hardy-Weinberg equilibrium
- Assume that p is the frequency of the dominant allele
- p² is the frequency of the organisms with homozygous dominant genotype
- Assume that q is the frequency of the recessive allele
- q² is the frequency of the organisms with homozygous recessive genotype
- 2pq is the frequency of the organisms with heterozygous genotype
- p+q = 1
According to the question, 900 out of 10000 rabbits are homozygous recessive
- This implies that q² = 900/10000= 9/100= 0.09
- So, q = 0.3
- The frequency of the recessive allele is 0.3
- p = 1-q = 1-0.3= 0.7
For organisms with heterogenous genotype, their frequency is 2pq
2pq= 2 x 0.3 x 0.7 = 0.42
In terms of percentage, 0.42x 100% = 42%
Therefore, 42% of rabbits in the population are heterozygous for the mutant Sp1 allele.
