Levels of HDL, LDL, and triglycerides in the blood: are simple traits. are influenced by many different genes. tend to cluster i
VLD [36.1K]

Answer:

are influenced by many different genes

Explanation:

A quantitative trait is a given phenotypic trait influenced by the combined effects of many genes and its environment. A quantitative trait locus (QTL) is a region of DNA (i.e., a <em>locus</em>) associated with the variation of a quantitative trait. In the last years, some QTLs correlated to the variation of HDL, LDL, and triglycerides levels were mapped in different genomic regions, thereby showing that these complex traits are regulated by the interaction of multiple genetic <em>loci</em>.

Why o we need a reverse compliment for pcr amplifying?
navik [9.2K]

Solution:

Since, DNA occurs as a double strand where each A is paired with a T and vice versa, and each C is paired with a G and vice versa. The reverse complement of a DNA sequence is formed by reversing the letters, interchanging A and T and interchanging C and G. Thus the reverse complement of ACCTGAG is CTCAGGT.

And DNA has two strands: Forward and reverse. Miseq is the technique to sequence the DNA for various purposes such as mutation detection, important for disease diagnosis. Hence, one need to find the mutations in both strands rather than only the forward to strand, to prevent false positives and other artifacts.  

This is the required answer.

In a population of 10,000 individuals of Monstera deliciosa, four individuals have a variegated phenotype that is caused by the
Mariulka [41]

Under the assumption of this population being in Hardy-Weinberg equilibrium,<em> the </em><em>probability</em><em> for the</em><em> fixation</em><em> of the var </em><em>recessive allele </em><em>equals 0.02 = 2%</em>

--------------------------------

<u />

<u>Available data:</u>

  • N = 10,000 individuals ⇒ Large population
  • 4 individuals have a variegated phenotype
  • variegated phenotype is caused by the recessive var allele
  • No selection, no additional mutation ⇒ we can assume Hardy-Weinberg equilibrium

We need to know the probability for the fixation of the var allele.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of variegated individuals in the population.

There are<u> 10,000 individuals</u>, and only <u>4 have variegated.</u>

So, the phenotypic frequency, F(Var) is 4/10,000 = 0.0004 =<u> 0.4%</u>

Since this is a recessive phenotype, this value equals the genotypic frequency, F(vv) = <u>0.4%</u>

Finally, we can get the allelic frequency by taking the square root of this value.

F(vv) = q² = 0.0004

f(v) = q = √0.0004 = 0.02 = <u>2%</u>

According to these calcs, the probability for the fixation of the var allele is <u>2%</u>, and the probability that all individuals express the variegated phenotype is <u>0.4%</u>.
