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

Observe the given Punnett square carefully and answer the following question.
What is the genotype of the homozygous offspring produced in box $d$ of the given Punnett square?

The phenotypic ratio of a Mendelian monohybrid cross is $-$

The crossing of a homozygous tall plant with a dwarf plant in the $F_2$ generation would yield plants in which ratio?

If $3^n$ is the theoretical number of different genotypes (where $n$ is the number of heterozygous gene pairs),then the number of different genotypes produced by a pea plant with the genotype $AaBbCcDdEeFfGg$ is:

$BB =$ alleles for black coat colour
$bb =$ alleles for brown coat colour
If the offspring of a cross between a black mouse $(BB)$ and a brown mouse $(bb)$ are allowed to interbreed,find the percentage of black-coated mice in the $F_2$ generation.
