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

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

If the order of base pairs in a DNA molecule is changed, what might occur?
tatuchka [14]

Answer:

When you change the order of the base pairs in an organism, that is called a mutation. There are three types of mutations: a deletion, an addition, and a substitution. In a deletion, one of the three bases in a codon is pulled out, or deleted.

Can you tell the difference between electromagnetic and mechanical waves?
mart [117]

Answer:

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.

How might water on the surface of the solid culture medium cause the disruption of colony formation?
lord [1]

Answer: There can be few reasons why surface on water can be harmful to the bacterial colony.

Explanation:

It is possible that while preparing the media for the bacterial colony that the constituents might not have been taken right proportion and water is more in it.

It tends to float on the surface and if the bacterial colony is not able to grow in such an environment it will led to the death of the colony.

There are chances that the mobility of the bacterial species increases in water and because of this there will be problems faced at the time of isolation.
