In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l
melisa1 [442]

The answers would be:

Genotype                Phenotype

     Tt                      Tall stemmed

     tt                       Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1  

<u />

<u>You can read on to see how this was done:</u>

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

<u>       t        t  </u>

<u>T |  Tt  |   Tt</u>

<u>t  |   tt  |   tt</u>

Let's list down the genotypes and phenotypic results.

Genotype        no.         Phenotype

     Tt                 2           Tall stemmed

     tt                  2           Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1

What is the difference between static and current electricity? give an example of each
Alenkasestr [34]
Static Electricity - the word static means 'at rest' - this kind of electricity exists when objects separated by an insulator has a build up of opposite charges. Because the attraction between these charges is so strong, they can flow even through great insulators. Ex: lightning, friction

Current Electricity - it makes electronic devices possible. There is a constant flow of charges in this type of electricity. In contrast to static electricity, current electricity is changing, dynamic and always on the move. Ex: starting a car, watching TV, using an electric stove.

Which choice best describes the purpose of most pharmacogenomic research??
zavuch27 [327]
Pharmacogenomic is defined as <span>the study of the role of the </span>genome<span> in </span>drug<span> response. It is a combination of Pharmacology and Genomics.

It studies how the genetic makeup of an individual affects his or her response to drugs. For example, a certain drug is administered to two individuals. One doesn't have any adverse reaction while the other one has. Pharmacogenomics will then conduct tests and study its results on why two individuals given the same drug have different reaction to it.</span>

OLEGan [10]

Answer:

Si existe variación en el acervo genético de la población, esto permite que la selección natural actúe sobre los rasgos de la población que permiten la adaptación al ambiente cambiante. Cuanta más diversidad hay en una población, mayor es la probabilidad de que la población pueda adaptarse a los nuevos cambios.
