Question

explain the concepts segregation of alleles and then independant assortment , pls and thankyou

Answer 1

Allele is the form of gene or 2 or more versions of a gene. Allele is a viable DNA coding that occupies position on chromosome.

The concept of segreggaton and independent assortment is based on principle of Mendel's Law as the seggregation was 1^st observed by Gregor Mendel.

The concept of seggregation.:  

Charecteristics and the gene transfer from one generation to other generation i.e., from parent to offsprings in Gametogeneis. there is 50% chances of getting specific trait from mother and 50% chance of getting trait from father. The trait are seperated in the process of gametogeneis. This is the only process applicable for Monohybrid cross. For example:

y}-----> yellow

Y}------>Green

so the offspring may get either yellow or green.

The concept of Independent Assortment:

The process is based on dihybrid cross two or more than two traits.

During the process of gametogeneis the two charecteristics are not depended on one another.

For example: Height: tt-----> short

TT------> Tall

y}-----> yellow

Y}------>Green

These two traits do not have equal influence on the offspring.

In one DNA if we have T T T T T t

Y Y y y y Y

In this case if we take the example of a plant the trait may have green or yellow flowers or the plant may be short or tall. So we get a lot of different combinations.

In independent assortment one character do not influence the effect of another character.
