blackpinf4ever $\sf{\underline{\underline{Transpiration\:pull:}}}$

$\bullet$ When transpiration occurs i. e., water evaporates from intercellular spaces into atmosphere, a tension or negative pressure is generated in xylem which is transmitted down to the roots.

$\bullet$ As a result, whole water column is lifted in apoplast pathway. The mass flow of water occurs, largely due to the transpiration pull.

$\text{\underline{\underline{Punnet\: square:}}}$

$\bullet$ A diagram that helps to predict the genotype, phenotype of the progeny in breeding experiment.

$\bullet$ The squares shown here are known as punnet squares (Check this attachment).

$\text{\underline{\underline{How\:to\:make\:a\:punnet\:square?}}}$

$\bullet$ So, let us take the example of cross between the two homozygous plants.

$\bullet$ Let us consider a single character height with genotype $\boxed{TT\:and\:tt}$

$\bullet$ The cross can be illustrated as: (Check this attachment)

$\text{\underline{\underline{In\:generation}}}$ $F_{2}:$

Genotypic ratio is:

$\implies$ $\boxed{TT\::\:Tt\::\:tt\:\:is\:\:1\::2\::\:1}$

Phenotypic ratio is:

$\implies$ $\boxed{3\::\:1}$
