It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.
eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.
Answer:
the first one air pressure
Meiosis I creates 2 diploid cells and meiosis II creates 4 haploid cells.
The correct answer is optionD 134/200.
The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has dominant allele and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.
The frequency is no of individual of desired trait divided by total number of individual.
The calculation is shown below:
