What will be the phenotypic ratio obtained from the selfing of a plant with the genotype $AABb$?

In $Drosophila$, the allele for a normal grey body colour $G$ is dominant to ebony body $g$. The following table summarises the results of several crosses:

$S.No$	Cross	Result
$I.$ Strain $1 \times gg$	All wild type
$II.$ Strain $2 \times gg$	$1$ wild type $: 1$ ebony
$III.$ Strain $3 \times gg$	All ebony
$IV.$ Strain $4 \times Gg$	$3$ wild type $: 1$ ebony

Which strains both have the genotype $Gg$?

If a homozygous tall plant is crossed with a dwarf plant,what will be the ratio in the progeny?

What is the phenotypic ratio obtained from a test cross of $F_1$ progeny in a monohybrid cross?

If two individuals with genotype $Bb$ are crossed and they produce two offspring,what is the probability that the second offspring will show the recessive trait,given that the first offspring shows the dominant trait?

When a pure tall plant is crossed with a pure dwarf plant,and the resulting hybrid plants are self-pollinated,what will be the phenotypic ratio of the offspring in the $F_2$ generation?
