Mendel’s law of independent assortment is applicable for
All genes in all organism
All genes of pea plant only
All linked genes only
All non-linked genes only
Mendel performed test cross to know the
Hybrid breakdown refers to the condition when offspring are physiologically inferior to the following generation
Test cross is useful to know the...
The leaf colour of certain plants is controlled by one gene. For that gene, the allele $G =$ orange and $g =$ green. You have a plant with orange leaves, but do not know whether that plant's genotype is $GG$ or $Gg.$
If you cross your unknown plant with one of the plants whose genotype is listed below, you will be able to determine your unknown's genotype. With which plant would you cross it?
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
