The principle that alleles live together without showing any blending is known as . . . . . . .

Mendel's $9:3:3:1$ ratio is due to the law of:

$A$ recessive trait is one that -

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?

The Law of Independent Assortment is possible only when:

If two opposite alleles come together,one finding morphological expression masking the other,the fact is described as the law of:
