Answer : Mendelian traits
1) A trait like eye color or height
2) Involves a dominant and recessive allele.
3) Predisposition to some diseases like diabetes and heart diseases.
4) These are equally likely to occur in males and females.
Sex linked trait
1) A trait like color blindness which affects many more men than women.
2) These are not equally likely to occur in male and female.
Explanation:
- The Mendelian inheritance is based on the laws proposed by Mendel.The traits that follow these laws are called as Mendelian traits.
- In an inheritance pattern, a Mendelian trait is the one which is controlled by only a single locus.
It is inherited in the manner that obeys Mendels laws -
1) Law of segregation - This law states that whenever gamete formation takes place each gene for a particular trait segregate from each other in such a way that each gamete carries only one allele.
2) Law of independent assortment- This law states that the genes for different traits segregate independent from each other during gamete formation.
3) Law of dominance- This law states that for every trait there are two alleles, one is dominant while the other is recessive.
Sex linked inheritance
It is the type of inheritance pattern followed by genes which are preesent on the sex chromosomes. Their inheritance varies from that of Mendelian pattern. If it is X linked dominant then each child of an affected mother has 50% chance of being affected whereas if it is recessive then a female can be a carrier or affected but a male will always be affected if it carries the allele.
