Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration is called
reciprocal cross
test cross
dihybrid cross
back cross
In wheat, when a green plant was self-fertilized, the progeny had $209$ green seedlings and $14$ white seedings. The above result indicates that
If enough crosses are made between male flies of the genotype $'Aa'$ and the female flies of the genotype $'aa'$ to produce about $1000$ offsprings. Which one of the following is the most likely distribution of genotypes in the offsprings
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 |

Do you think Mendel’s laws of inheritance would have been different in the characters that he choose were located on the same chromosome ?
