If the frequency of a dominant allele in a population in equilibrium is 0.35, then the frequency of the corresponding recessive
Nadusha1986 [10]

Answer:0.8775

Explanation:formula for gene frequency is p+q=1

where p is the dominant allele and q is the recess allele.

Given than p=0.35

P^2=0.35^2=0.1225

q=1-p

q=1-0.1225=0.8775

Explain the purposes of gene expression studies. Describe the use of DNA microarray assays and explain how they facilitate such
denis-greek [22]

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
