prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

inessss [21]

The best precaution against carbon monoxide poisoning is to keep air moving through the boat.

Carbon monoxide is a potentially deadly gas that is produced any time a carbon-based fuel burns. If you suspect carbon monoxide poisoning you must do the following: open doors and windows, turn off gas appliances. To determine if a person is poisoned by carbon monoxide you may look for the following signs and symptoms: dull headache, weakness, dizziness, nausea or vomiting, shortness of breath, confusion, blurred vision, loss of consciousness.

weeeeeb [17]

He needs to be careful to document his sources about the problem of invasive species.

<h3>What is Invasive species?</h3>
  • An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
  • Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
  • Invasive species are one of the largest issues our natural environments have ever faced.
  • Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
  • This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
  • Additionally, the extension of existing imported specie's ranges is made possible by climate change.
