Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is $\frac{1}{2}$ curly tails, $\frac{1}{4}$ straight tales, $\frac{1}{4}$ tailless

(what organelle is this) Passive transport is taking place across this thin cell covering causing the muscle cells to contract.

deff fn [24]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete. However, the cell organelle involved in transportation of molecules in the cell is the cell membrane. This cell membrane can be said to be cause of several forms of transportation in and out of the cell - this is because the membrane is a selective barrier. While some substances/molecules move through diffusion by moving with the concentration gradient (as in the case of passive transport, others move against the concentration gradient requiring energy to cause the transportation (as in the case of active transport).
