The results of the di-hybrid cross of pea plants with round and yellow seeds was the evidence that Mendel fond that supported his law of independent assortment.
<u>Explanation:</u>
Law of independent assortment states that the alleles of two different genes are inherited independent of each other. The law of independent assortment was formulated by Gregor Mendel . Cross of a pea plant with yellow and round seeds with a pea plant having green and wrinkled seeds gave evidence of the law of independent assortment.
When it comes to seed color yellow color is dominant to green. When it comes to seed shape round seed is dominant to wrinkled seed. Let the letter R represent round seed and R represent wrinkled seed. The letter Y represent yellow seed and letter y represent green seed.
The genotype of pea plant with round and yellow seed is RRYY and the genotype of round and wrinkled is rryy. The cross between round yellow and wrinkled green can be represented as follows
Gametes RY ry
F1 generation RrYy RrYy RrYy RrYy
All the plants of the F1 generation have round and yellow seeds.
The F1 generation plants are then bred together
RRYY RrYY RRYy RrYy RrYY rrYY RrYy rrYy RRYy RrYy RRyy Rryy RYy rrYy Rryy rryy
r
Are the progenies with phenotypes like round yellow, round green, wrinkled yellow and wrinkled green.
The combination of the characters of roundness and color is observed in the F2 generation proves that the characters of round and yellow as well as wrinkled and green doesn’t appear strictly in combination. This means that they are independently assorted which proves the law of independent assortment.
answer:
this is the cell theory, which was proposed by Theodor Schwann in 1839
explanation:
- in biology, cell theory is the historic scientific theory
- it states that living organisms are made up of cells, they are the basic structural/organizational unit of all organisms and all cells come from pre-existing cells.
Yes this is a true statement
<u>Answer</u>: D. calcium chloride
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
