Cross between $F_1$ plant and recessive female plant is called
Back cross
Test cross
Out cross
Mutation
In Mendelian monohybrid cross, phenotypic ratio in $F_2$ is $3:1$. How many types of gametes are formed in $F_1$ generation
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:
If a cross is made between $AA$ and $aa$, the nature of ${F_1}$ progeny will be
When a heterozygous dominant is crossed with homozygous recessive than ratio of progeny will be
Genes which code for a pair of contrasting traits are known as ........
