Answer:

Option A, 100 \\%

Explanation:

Let the allele for non freckled trait be represented by “f”

The allele for freckled trait be represented by “F”

Let us consider that freckled trait is dominant over the non – freckled trait.  

The genotype for a non – freckled parent will be “ff”

The genotype for a homozygous freckled parent will be “FF”

When a cross is carried out between a non – freckled parent and a homozygous freckled parent , the following offsprings are produced –  

f f

F Ff Ff

F Ff Ff

 

Thus, all the four offsprings have heterozygous genotype. Since we assumed that freckled trait is dominant over the non – freckled trait, all the offsprings would be freckled.  

Thus, the probability of a child having freckles would be

\frac{4}{4} * 100\\= 100\\%

Thus, option A is correct.

What are the frequencies of each offspring genotype in a cross between rr female and a rr male?
Vera_Pavlovna [14]
Since the male and the female have recessive alleles of this gene, all of their offspring will be like that too.
rr x rr cross will result in 100% of the offspring with the genotype: rr

R- dominant (but none of the parents has this allele)
r- recessive

aliina [53]
<span>The Golgi apparatus </span>is responsible for packing proteins from the rough endoplasmic reticulum into membrane-bound vesicles which then trans locate to the cell membrane. At the cell membrane, the vesicles can fuse with the larger lipid bi layer, causing the vesicle contents to either become part of the cell membrane or be released to the outside.

Which of the following statements best defines the term operon? a. An operon is a region of RNA that consists of the coding regi
denis-greek [22]

The correct answer is: c. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.

Operons contain cluster of genes that are transcribed together into mRNA or are not expressed at all. Formed mRNA undergos splicing to create monocistronic mRNAs so that can be translated separately. Operons are more often found in prokaryotic cells but it can appear in eukaryotic cells and in viruses.
