Small molecules and nonpolar molecules are the ones that can move most easily across the lipid bilayer and enter the cell. Diffusion is the process that causes these molecules to move in or out of the cell. At this point the rate at which individual molecules enter and leave will be equal.

Using the information from problem 11, scientists do a further test cross using a heterozygote for height and nose morphology. T
mote1985 [20]

Answer:

The recombinant frequency between T and S is  18%;

The correct Sequence of genes is T-A-S

Explanation:

The table below shows the recombinant frequency between heterozygous height and nose morphology:

Tall-uptrend snout                            40%                            Expected

Dwarf-downtrend snout                   42%                            Expected

Dwarf-uptrend snout                         9%                             Recombinant

Tall-uptrend snout                             9%                             Recombinant

Sum Total                                           100%

To calculate the recombinant frequency; we have :

=9+9

=18%

Hence, the recombinant frequency between T and S = 18%

The determinant of the corect sequence of the genes is  T-A-S
