Ans.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
Answer:
We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.
Explanation:
Reactivity : It refers to the affinity of a substance to combine with other substance .
Elements are mainly of two types :
In terms of metals or non metals it can be defined as tendency to loose or gain electrons .
- On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
- But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .
