What is likely phenotypic ratio resulting from a dihybrid cross with alleles showing epistatic interactions?

Biology
1 answer:
Mashutka [201]3 years ago
4 0

The answer is one (1) phenotype. This is because epistasis interaction of gene alleles involves the masking of one phenotype of an allele of a gene (at one or more loci) by the other.  Alternatively, the epistatic alleles may interact to cause a modification of a phenotype.

If a crystal of potassium permanganate is placed on agar and after 15 minutes the diameter of the area over which the dye has sp
Vadim26 [7]

Answer:

Diffusion rate is 1.96 × 10^{-3} cm^{2}/s

Explanation:

Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.

diffusion rate = \frac{area}{time}

Given that; diameter = 15 mm, time = 15 minutes.

The dye spread in a circular form, so that;

area = \pir^{2}

r = \frac{diameter}{2} = \frac{15}{2} = 7.5 mm = 0.75 cm

area = \frac{22}{7} × (0.75)^{2} = 1.7679 cm^{2}

time = 15 minutes = 15 × 60 = 900 seconds

So that;

diffusion rate = \frac{1.7679}{900}

                      = 0.0019643 cm^{2}/s

Diffusion rate is 1.96 × 10^{-3} cm^{2}/s

Differentiate between competitive inhibitors and non-competitive inhibitors
DanielleElmas [232]

Explanation:

 main difference between competitive and noncompetitive inhibition is that competitive inhibition is the binding of the inhibitor to the active site of the enzyme whereas noncompetitive inhibition is the binding of the inhibitor to the enzyme at a point other than the active site.

What is the main difference between the null and the research hypothesis? What is the importance of assuming the null hypothesis
Ksivusya [100]

Answer:

The null hypothesis is a general statement that states that there

is no relationship between two phenomenons under

consideration or that there is no association between two groups.

A hypothesis, in general, is an assumption that is yet to be proved

with sufficient pieces of evidence.

1.If a DNA molecule has 40% Cytosine, what percent of it would be Adenine?
andrey2020 [161]

Answer:

The correct answer is -

1. Adenine - 10%

2. A-T and C-G always in DNA.

Explanation:

1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.

So, Cytosine = 40%, Guanine= 40%

total = 80%

therefore, the A and thymine would be - 100 - 80 = 20

A+T = 20

A= 10, and, T = 10%

2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.
