Which one of the following cannot be explained on the basis of Mendel's law of Dominance ?
The discrete unit controlling a particular character is called a factor
Out of one pair of factors one is dominant, and the other recessive
Alleles do not show any blending and both the characters recover as such in $F_2$ generation
Factors occur in pairs
Test cross is useful to know the...
The important things to remember are that chromosomes as well as genes occur in ...$A$.... The two alleles of a gene pair are located on homologous sites on ...$B$... chromosomes
Choose the correct choice for $A$ and $B$
When two individuals are similar in external appearance but differ in their genetic make up, they are called as
The percentage of heterozygous individuals obtained in $F_2$ generation from selfing the plants with genotype $Rr$ would be
To determine heterozygousity of a cross, one has to perform
