The answer would be 3), what is the effect of crop selection for pest-resistance on the sale of green salad in grocery stores.
(This is a direct/tangible variable that can be measured)
Answer:
<h3>Genotype frequencies</h3>
25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
<h3>Phenotype frequencies</h3>
75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d <em>Dd dd</em>
<em />
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
Answer:
1 : 5
Explanation:
Ratio is used to show the relationship between two amounts. It tells how many one value is contained within another value. Ratio can be used to compare the size of two or more numbers in relation to each other.
The comparison between this two numbers or quantities is done and expressed by division.
Ratio of triangles to squares = number of triangles : number of squares
Ratio of triangles to squares = 4 : 20
Ratio of triangles to squares = 1 : 5
In any scientific paper you can find th eprocedure part which should in detail explain how the procedure of a particular experiment was performed. Using these instructions we should be able to replicate an experiment, if the results that were obtained in the previoues experiments were correct of course.
