Match List $I$ with List $II$
List $I$ | List $II$ |
$A$. Two or more alternative forms of a gene |
$I$. Backcross |
$B$. Cross of $F_1$ progeny with homozygous recessive parents | $II$. ploidy |
$C$. Cross of $F_1$ progeny with any of the parents | $III$. Allele |
$D$. Number of chromosome sets in plant | $IV$. Test cross |
Choose the correct answer from the options given below:
$A-II, B-I, C-III, D-IV$
$A-III, B-IV, C-I, D-II$
$A-IV, B-III, C-II, D-I$
$A-I, B-II, C-III, D-IV$
For obtaining hybrid ratio which characters of the plant are taken into account
What is the cross between the progeny of $F_1$ and the homozygous recessive parent called ? How is it useful ?
The first "geneticist'' was
$A$ : Dominance is not an autonomous feature of a gene.
$R$ : It depends as much on the gene product and the production of a particular phenotype from this product
In pea hybrids between red flowered and white flowered strains were crossed back to pure red flowered strain. The progeny of this cross will have
