Scale coloration of lizards has a complete dominance relationship where green scales are dominant over blue scales. there are 1,
024 individuals with the genotype gg, 512 individuals with the genotype gg, and 64 individuals with the genotype gg. find: the frequency of the dominant and recessive alleles and the frequency of individuals with dominant, heterozygous, and recessive genotype.
Frequency of recessive allele (q) = 0.2 or 20 percent
Frequency of dominant allele (p) = 0.8 or 80 percent
The frequency of homozygous dominant individuals (p²) = 0.64 or 64 percent.
The frequency of homozygous recessive individuals (q²) = 0.04 or 4 percent.
Frequency of heterozygous dominant indivduals (2pq) = 0.32 or 32 percent.
It can be explained with the help of the Hardy-Weinberg equation:
p + q = 1
p² + q² + 2pq = 1
q² represent the frequency of individuals with homozygous recessive genotype. It can be calculated by dividing the number of individuals with homozygous recessive genotype with a total number of individuals in a population.
It's no longer the dead-end of the carbon cycle. Since the industrial revolution, this material has been taken out of the ground (by Oil and Gas companies) which is for the most part subsequently burned - of which the final by-product is CO2. This fossil material also goes into making plastics and other chemicals - so the "dead-end of the carbon cycle" is not quite so straight forward anymore.
