True-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) a

mina [271]

Answer:

The correct answer is -

Possible F2 offspring genotypes and phenotypes:

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Explanation:

In this case, the genes 's' and 'L' and genes 'S' and 'l' are linked, they will be passed on to the gamete together.

The cross would be as follows:

F1:

Parents: singed bristles and normal wings x normal bristles and vestigial wings

Genotype: ssLL SSll

Gametes: sL Sl

F1: SsLl ( normal bristles and normal wings )

For F2,

Parents: normal bristles and normal wings x singed bristles and vestigial wings

Genotypes: SsLl ssll

Gametes: SL, Sl, sL, sl

Cross:

SL Sl sL sl

sl SsLl Ssll ssLl ssll

Thus the possible offspring will have -

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

What enlightenment principles did the state constitutions all put into practice?

Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".

<u>Answer:</u> Option B

<u>Explanation:</u>

Global circulation is defined as the global connection of winds, through which the requisite heat transport from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.

The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.
