Which of the following statements regarding genotypes and phenotypes is false? Alleles are alternate forms of a gene. The expres

sed physical traits of an organism are called its phenotype. The genetic makeup of an organism constitutes its genotype. An organism with two different alleles for a single trait is said to be homozygous for that trait.

Answer:

D

Answer:

D

Explanation:

Homozygous mean a pair of alleles that are the same. Hence the root word homo- which means same. If the alleles were different, we would call this pairing a heterozygous pair, with the root word hetero- meaning different. An example of a homozygous pair would be AA, two dominant allele, or aa, two recessive alleles, while a heterozygous pair would be Aa, one dominant and one recessive allele.

Which best describes the cell theory
Neko [114]
Each cell is alive even if it is part of a multi celled body, and all living organisms consist of one or more cells. Also, cells reproduce by dividing so it follows that all existing cells must have arisen by division of other cells. As a cell divides it passes it hereditary material- its DNA- to offspring.

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
