Answer:
By checking the proportion of those affected by the trait in relation to gender within the population of the offspring
Explanation:
If a trait is sex linked, such trait will be found more in the male sex compared to the female sex within the population.
The male has XY chromosome and as such only needs a copy of the affected allele in order to be affected for the trait. A female has XX chromosome and as such needs two copies of the affected alleles in order to be affected for the trait.
Hence, the proportion of affected male always outweigh the proportion of affected female in a population as far as sex-linked trait is concerned.
<em>Consequently, a scientist might be able to determine whether a trait is sex-linked by observing the proportion of male to female affected by the trait within the offspring's population.</em>
The correct answer that would best complete the given statement above would be TOO SMALL. Here is the complete statement. <span>If a cell cannot move enough material through its membrane to survive, then the ratio of its surface area to volume is TOO SMALL. Hope this answer helps you. </span>

Complete question:
In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.
1. In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is -------
2. If you examine 100 F₁ plants from the testcross and find that they all have purple flowers with tall stems, you should conclude that the genotype of your original pea plant is -------
3. If you examine 100 F₁ plants from the testcross and find that 44 have purple flowers with tall stems and 56 have purple flowers with short stems, you should conclude that the genotype of your original pea plant is -------
4. If you examine 100 F₁ plants from the testcross and find that 53 have purple flowers with tall stems and 47 have white flowers with tall stems, you should conclude that the genotype of your original pea plant is
-------
5. If you examine 100 F₁ plants from the testcross and find that 23 have purple flowers with tall stems, 26 have white flowers and tall stems, 24 have purple flowers with short stems, and 27 have white flowers with short stems, you should conclude that the genotype of your original pea plant is

Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
