<u>Answer</u>: The allele for short pea plants is masked during the F1 generation, but it is still present in the genotype.

<u>Explanation</u>:

  • There are two types of alleles present for a given gene. One allele is the <em>dominant</em> allele and the other is <em>recessive</em>.
  • Whenever a dominant allele is present it is able to <em>mask the expression</em> of the recessive allele. Therefore, whenever a dominant allele and recessive allele are present together (heterozygous condition) the phenotype is that of the dominant allele.
  • Whenever, the phenotype of the recessive allele appears it is necessary that the recessive alleles have to be in homozygous condition.
  • Thus, in the <em>P1</em> generation, the short pea plants are there as there is <em>homozygous condition (tt)</em> and the same happens in the case of<em> F2</em> generation. However, in the <em>F1 generation,</em> all the progenies have the genotype <em>Tt, this is a heterozygous condition</em> and thus, the short pea plants are not seen in F1.
  • Such a condition arises when TT (tall plant) is crossed with tt (short plant) in the P1 generation.
  • The diagram attached shows the punnet square for such a cross and the results of the cross is the F1 generation. As seen from the punnet square all the F1 progenies are of Tt genotype and, the phenotype of tall plants is produced as T (tall) is dominant over t(short) allele.

The graph below depicts the frequency of expression of the range of leg lengths in a population of crickets:
Ilia_Sergeevich [38]

The correct answer is option:

The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.

The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.

The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.

What are the three types of osmosis? What happens during each phase?
Vanyuwa [196]
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .

A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.

A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
