A graphical representation to calculate the probability of all possible genotypes of offspring in a genetic cross is called as:
1. Forked line diagram
2. Punnett square
3. Pedigree chart
4. Idiogram

Which one of the following cannot be explained on the basis of Mendel's Law of Dominance?

(1) The discrete unit controlling a particular character is called a factor

(2) Out of one pair of factors one is dominant, and the other is recessive

(3) Alleles do not show any blendings and both the characters recover as such in F₂ generation.

(4) Factors occur in pairs

What is the means of segregation in Law of segregation? 

(1) Allelic separation

(2) Chromosomal separation

(3) Crossing over

(4) Linkage

Law of segregation can be proved with

1.  The presence of dominant genotype in ${\mathrm{F}}_2$

2.  The presence of recessive genotype in ${\mathrm{F}}_1$

3.  The presence of recessive homozygous in ${\mathrm{F}}_2$

4.  The presence of a heterozygous individual in ${\mathrm{F}}_2$
