Interesting Q & A session by one of the curious student

AdminAcademics

Jaivikshastram is an open forum for posting questions and Team Jaivikshastram get back to you soon. This is one of the first Q & A we got.

Yogesh :

How recesive traits are masked by dominant traits ?

Shaktiprasad : 

Before answering the question we should know difference between dominant and recessive allele.

Recessive allele is nothing but the mutated form of the dominant allele.
 eg. For height T and t where T is responsible for synthesis of Gibberellic acid.

The dominant or recessive decided is at organism level. But at molecular level all alleles are co-dominantly expressed.

For ex. In sickle cell anemia if both alleles expressed are sickle that is nonfunctional alleles then produce sickle shape red blood cell (RBC) and if heterozygous then the produce intermediate shape RBC to that of the normal.

At individual level the person may  have sickle anemia of carrier for the disease but at molecular level it have both nonfunctional or semi functional alleles.

We can also take an example of T and t in accordance with the plant but in plant development environment plays a crucial role.

As recessive is non-functional then there is nothing like masking as such.

Thanks for being curious Yogesh, Keep asking Questions, be curious.

Yogesh :

Firstly i would like to thank you. you cleared me that, both genes are expressed at molecular level, but what about pea plant height in F1 heterozygous condition ?

GauravGG :

Height is the phenotype based on plant hormone Gibberellic acid. In F1 we get all tall plants because expression of t is much more less than T that we cannot observed it in phenotype. In F1 all pea plants become tall whether the genotype is TT/ Tt .

 

 

Passion for Teaching

Team Jaivikshastram works on values which says,

 

                             “Be passionate to make Others”

 

Today article published in current science talks about crucial need of motivated and committed teachers. Giving justice to the post which is offered to teachers is a hard task. As article says teacher is a driver of classroom and teacher should drive the class with the fuel of motivation.

We are aiming to export our teachers throughout the world but before that we should strengthen ourselves with all the minor things required.
