4.Principles of Inheritance and Variation
normal
A tobacco plant which is heterozygous for albinism $(a\, recessive\,character)$ is self pollinated if $1200$ seeds are subsequently germinated, how many of the seedlings would have the parental genotype
A
$300$
B
$600$
C
$900$
D
$1200$
Solution
(b) $XX × Xx ……$ Parents
$\downarrow$
$XX Xx Xx xx ……. $ $F_1$ hybrid
In $F_1$ generation half of the total offsprings represent parental genotype i.e., $Xx$. Therefore out of $1200$ seedling $600$ will have parental genotype.
