What is the correct sentence?
lorasvet [3.4K]

Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).

Explanation:

During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.

Subsequently, this mRNA is then used as template to create a protein by a process called translation.

Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.

The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.

In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).

iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>
