The right answer is True.
Thanks to several genetic manipulations, a bacterium has been transformed into a plant exclusively dedicated to the production of biofuel. The microorganism expelling the precious fatty acid out of the cell, this synthetic route circumvents the expensive step of extraction and purification.
The production of this fuel faces several problems. It must achieve sufficient production rates to meet the demand for biofuel while being competitive with oil.

Answer:
0.035
Explanation:
<u>cv+ is the wild-type dominant allele over cv, therefore:</u>
- cv+cv+ and cv+cv cause wild-type phenotype for crossveinless
- cv cv causes the crossveinless phenotype
<u>Sb is a dominant mutant allele over wild-type Sb+, therefore:</u>
- Sb Sb and Sb Sb+ cause Stubble phenotype
- Sb+ Sb+ causes wild type phenotype for Stubble
<h3><u>Test cross</u></h3>
It's the cross between the heterozygous female with a homozygous recessive male. Remember that cv and Sb+ are the recessive alleles.
X 
-The male produces only 1 type of gamete: cv Sb+
-The female produces 4 types of gametes:
- cv Sb+ ] Parental
- cv+ Sb ] Parental
- cv Sb ] Recombinant
- cv+ Sb+ ] Recombinant
The genes are linked and separated by 7 map units. A distance of 7 mu means that 7% of the resulting gametes will be recombinant. Because there are 2 possible recombinant gametes, each of them will appear in 3.5% of the cases.
The genotypes and proportions of the offspring resulting from the test cross can be seen in the Punnett Square. The phenotypically wild-type individuals will have the genotype cv+ Sb+ / cv Sb+ (heterozygous for crossveinless and homozygous recessive for Stubble) and a 0.035 proportion.
A cross between individuals that are heter0zyg0us for two different traits is a dihybrid cross. <em>A cross between two individuals that are heterozygous for eye and skin color would be an example of a _</em>dihybrid<em>_ cross.</em>
----------------------
Dihybrid crosses involve individuals that expresses two different traits and are heter0zyg0us for each of them.
So let us imagine we are studing the characters eye color and skin color. Let us assume that both of them are coded by single diallelic genes.
For eye color there is
- Dominant allele B that codes for brown eyes
- Recessive allele b that codes for blue eyes
For skin color there is
- Dominant allele A that codes for black skin
- Recessive allele a that codes for white skin
So, an individual that is heter0zyg0us for both of them, is BbAa.
If this person crosses to another person with the same genotype, we are talking about a <u>dihybrid cross</u>, because two dibybrid individuals are involved.
Cross: BbAa x BbAa
According to this information, we can aswer the question:
<em>When crossing two individuals that are heterozygous for eye and skin color we are referring to a</em><em> dihybrid cross.</em>
