The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )

The phenotype of the cross is 3 : 1 ( Tall : Dwarf )

<u>Explanation:</u>

Given:

Cross between two heterozygous tall pea plant

Let the allele of a tall pea plant be represented by T and for dwarf be t

In heterozygous condition, the genotype would be Tt

Cross between Tt X Tt is shown in the diagram inserted.

According to the cross performed:

The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )

The phenotype of the cross is 3 : 1 ( Tall : Dwarf )

Answer:

It is based on the size of seismic waves

Explanation:

Generally, the size of an earthquake is called its magnitude.

Earthquake’s magnitude is defined as the measure of the amplitude of the seismic waves. A seismometer or seismographs are used to measure seismic waves. So, the statement describes one aspect of an earthquake’s magnitude is that Earthquake’s magnitude depends on the size of seismic waves.

Earthquake’s magnitude is measured by the Richter magnitude scale.

Hence, the correct answer is It is based on the size of seismic waves.

The final pattern you wish to obtain expresses the UASG-GFP construct only in cell C2. How will you drive UASG-GFP expression sp

Nat2105 [25]

Answer:

Explanation:

Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.

Therefore, the only cell that expresses GAL4 is cell C-2.

The arrangement is:

1. Construct 1 should express GAL80

2. Construct 2 should express GAL80

3. Construct 3 should express GAL4

4. Construct 4 should not be used
