(d) It is an example of test cross.
An organism with two identical alleles for a given trait is
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
Mendel’s law of sagregation is applicable to
Assertion : Cross of $F_1$ individual with recessive homozygous parent is test cross.
Reason : No recessive individual are obtained in the monohybrid test cross.
Dominant allele are expressed in
