Was there any noticeable effect on the germination rate of the radish seeds as a result of the ph? compare and contrast the grow
zubka84 [21]
Doubtlessly the germination rate of the radish seeds is more noteworthy when the pH is more unbiased, similar to when putting in water. There wasn't any distinction in the development of the radish seeds between the soluble and acidic arrangements in my analysis. The seeds did not develop in either arrangement. The radish seeds appeared to endeavor to develop in the acidic arrangement. The reason I say endeavored to develop is on account of you could see greenish spots where the seeds were put. The radish seeds had no adjustment in the antacid arrangement. Neither one of the solutions is a decent situation for radish seeds to develop.

A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (
Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97
