Determine the number of possible types of gametes produced by an organism with the genotype $AABBCC$.

$A$ heterozygous tobacco plant for albinism is self-pollinated,and $1200$ seeds are subsequently germinated. How many of the offspring will have the parental genotype?

If the genotype of an offspring is $TT$,determine the number of possible gamete types produced by it.

If enough crosses are made between male flies of the genotype $Aa$ and female flies of the genotype $aa$ to produce about $1000$ offspring,which one of the following is the most likely distribution of genotypes in the offspring?

Mendel proposed the Law of Purity of Gametes based on:

When a heterozygous dominant is crossed with a homozygous recessive,the ratio of the progeny will be:
