Important Questions on Mendelian Genetics
Blue eye colour in human is recessive to brown eye colour. The expected children of a marriage between a blue-eyed woman and a brown eyed man who had a blue-eyed mother will be-
A tobacco plant heterozygous for albinism is self-pollinated, and 1200 seeds are subsequently germinated. How many seedlings would have the parental genotype?
If a cross is made between two individuals each having genotype Bb, two offsprings are obtained. Out of these first has dominant trait. What is the probability that the second offspring will exhibit recessive trait?
If there were only parental combinations in of a dihybrid cross then Mendel might have discovered:
If Mendel might have studies 7 pairs of characters in a plant with 12 chromosomes, instead of 14 then:
Which law would have been violated if Mendel had chosen eight characters in garden -pea :
If Mendel has chosen to study traits determined by linked genes he would not have discovered
In a dihybrid cross, when one pair of alleles show incomplete dominance, genotypic ratio comes to
According to Mendel, "factors" or "genes"
Mendel observed that all the progeny plants.
The colour based contrasting traits in seven contrasting pairs studied by Mendel in pea were
Some of the dominant traits studied by Mendel were :
Among the seven pairs of contrasting traits in pea plant, studied by Mendel, the number of traits related to flower, pod and seed respectively was:-
How many types of genetically different gametes will be produced by a heterozygous plant having the genotype AABbCc?
Mendel's Principle of segregation means that the gamete cells always receive :-
A cross between pure tall pea plant with green pods and dwarf pea with yellow pods will produce how many tall plants, out of 16?
Mendel's laws of inheritance are applicable on the plants which :
What result Mendel would have got when he self pollinated a dwarf plant ?
If hybrid red-flowered plants of pea are crossed back to the pure red-flowered parent, the progeny will show:
A pure tall and a pure dwarf plant were crossed to produce offspring. Offsprings were self crossed, then find out the ratio between true-breeding tall to true-breeding dwarf:
