Marizza181 [45]

Answer:

2% of the progeny will be double crossovers for the trihybrid test cross

Explanation:  

By knowing the positions of genes, we can estimate the distances in MU between them per region.

  • Genes A and B are 10 map units apart (Region I)
  • Genes B and C are 20 map units apart (Region II)
  • Genes A and C are 30 map units apart

----A-------10MU--------B-------------20MU-------------C---

             Region I                      Region II  

We can estimate the recombination frequencies by dividing each distance by 100.

• recombination frequency of A-B region = 10MU / 100 = 0.10

• recombination frequency of B-C region = 20MU / 100 = 0.20

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.10 x 0.20 = 0.02        

2% of the progeny will be double crossovers for the trihybrid test cross

Temporary storage sites in the cytosol for substances such as pigments or nutrients are called?
NemiM [27]

Temporary storage sites in the cytosol for substances such as pigments or nutrients are called inclusions.

Pigments are the compounds that have a certain color and provide color to other structures indie the body. For example in plants chlorophyll is the pigment that provides green color to the leaves and stem. In humans and other animals, the blood consists f red colored pigment called hemoglobin.

Inclusions are the non-living objects inside the cell. They can be anything like pigments or any other molecules, that performs no function inside the cell. They are also called ergastic substances and do not even have any membrane.

Select the Two characteristics that these proteins have in common.
Sunny_sXe [5.5K]

Answer:

C, D

Explanation:

The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).
