What are the genotypic and phenotypic ratios

Chemistry
2 answers:
inessss [21]3 years ago

- Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)

- Phenotype is the morphology of a living organism .(the trait you usually observe while looking/tracking the organism)

Example:

- In the flower of a pea plant there are a pink color(RR) or (Rr) and a white color(rr).

- When crossing two hybrid ( with two different letters) pink colors,

P  :     Rr        ×      Rr  

G :      R    r        R    r    

F1 :  RR   Rr    Rr    rr

- the phenotype ratio will be  (3 pink : 1 white)

- the genotype ratio will be  [1 (RR) : 2 (Rr) : 1 (rr)]..

What are the parts of the atomic theory
Anvisha [2.4K]

Answer:

Explanation:

Dalton’s Atomic Theory  

All elements are composed of tiny indivisible particles called atoms.

All atoms of the same element are identical.

Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).

Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).

Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).

Express scientific notation 12 thousandth
Sever21 [200]
12 thousandth is the same as 0.012, so to put something in scientific notation you move the decimal point to the left or right until it is between the first two numbers. So:

Moving the decimal for 0.012 to between the first two numbers, we get: 1.2

For every move of the decimal place to get there, we divide/multiply by 10 each time. In this case, we multiply by 10 each time.

To get to 1.2, we had to move the decimal 2 times, so the answer is 1.2×10^-2

When you move the decimal to the right, the value of the power is negative, and when you move it to the left it is positive.

The forensic technician at a crime scene has just prepared a luminol stock solution by adding 16.0 g of luminol into a total vol
nikitadnepr [17]

 The  molarity  of  the stock solution of  luminol  is 1.2 M


 <u><em>calculation</em></u>

step 1:  find the moles  of  luminol  using   (moles=  mass/molar mass)  formula


molar  mass  of Luminol= 177 g/mol

moles  is therefore= 16.0 g/ 177  g/mol=0.0904 moles


Step  2:  find the molarity  using (molarity= moles/volume in liters)  formula

     convert  Ml  into liters =  75.0/1000= 0.075 L

  molarity is therefore= 0.0904 moles/ 0.075 L= 1.2M

I will brainliest you if you answer my question thank you pls read the photo.​
kati45 [8]

Answer:

The flow of information from the starting material DNA to the final product protein is depicted in the core dogma of molecular biology. That is depicted in the diagram. It also shows where each step takes place. Replication is the process of passing information from one DNA to another DNA, as seen in the diagram. This occurs within the nucleus. Why is each process carried out in a certain location? It is because it is where the essential substance may be found. As a result, replication occurs in the nucleus, where the necessary enzymes and ingredients for replication are present.

I hope I helped! ^-^
