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.

Luden [163]

Hello!

We all are very well familiar with Mendel's laws of inheritance. Just recalling Mendel's  law of independent assortment that states, "alleles of different genes are inherited independently of one another".

Here we have two traits, and we want to know how the alleles of these traits will assort independently during the formation of gametes from two parents.

The two traits are:

  1. Flower color ( Can be purple or white)
  2. Seed shape   (Can be round or wrinkled)

Here the alleles of the traits are represented by alphabets as:

  1. purple flowers: P
  2. white flowers: p
  3. round seeds: R
  4. wrinkled seeds: r

We have parent one as PpRr  

The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 1.

  • Gamete 1: PR  
  • Gamete 2: Pr  
  • Gamete 3: pR  
  • Gamete 4: pr  

We have parent two as PpRr  :

The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 2 as well.

  • Gamete 1: PR  
  • Gamete 2: Pr  
  • Gamete 3: pR  
  • Gamete 4: pr

This shows that there is not restriction that the allele for wrinkled seed r will go with allele of white flower p because its recessive or allele of round seeds R will go with allele of purple flowers P because  its dominant. There is no restriction when alleles are assorting into gametes and they can go randomly as per nature's choice with any one.


Hope it helps! :)
