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.
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
Answer: the introduction, the body, and the conclusion
Explanation:
An editorial piece is meant to show the opinion of the newspaper on a certain issue. It is usually written by the senior editor or the publisher and is the first article on the written piece.
Editorials follow a common writing structure that begins with an introduction where the issue is introduced. Discussions are then made in the body and the conclusion will then round up the piece.
The process of cellular differentiation is a direct result of a differiental
Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
Sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
<h3>What is Meiosis?</h3>
Meiosis is a particular type of cell division by which gametes (germinal cells are generated) through two division cycles known as Meiosis I and Meiosis II.
During Meiosis I homologous chromosomes are separated, thereby ensuring the correct segregation of sister chromatids during Meiosis II.
In conclusion, sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
