Which Mendelian idea is depicted by a cross in which the F1 generation resembles both the parents?
In Co-dominance F1 generation resemble both the parents. Ex :Blood group inheritance.
If two persons with ‘AB’ blood group marry and have sufficiently large number of children these children could be classified as ‘A’ blood group: ‘AB’ blood group: ‘B’ blood group in 1 : 2 : 1 ratio. Modern technique of protein electrophoresis reveals presence of both ‘A’and ‘B’ type proteins in ‘AB’ blood group individuals. This is an example of :
ABO blood group system in human beings is an example of codominant, dominant recessive and multiple alletes. Blood groups are controlled by the gene I located on 9th chromosome that has 3 multiple alleles,out of which any two are found in a person. In codominance both gene express it self completely.
Phenylketonuria, Huntington’s disease and sickle cell anaemia are caused respectively due to disorders associated with
Human skin colour is controlled by several gene pairs. Let us assume here that there are just three gene pairs on different chromosomes and that for each pair there are two alleles-an incompletely dominant one that codes for melanin deposition and an incompletely recessive one that codes for no melanin deposition. If a very dark skinned person marries a very light skinned woman, what will be the chance that their offspring will have very dark skin ?

Right handedness is dominant over left handedness. Most probable genetypes with 2 right handed parents having left handed child is
A cross between parents with A and AB blood groups results in the offspring with which of the following blood groups?
Absence of one sex chromosome causes
The chromosome constitution 2n – 2 of an organism represents
