Question

Use the Artificial Selection Interactive to increase the average flowering head size of the sunflowers and answer the questions. Why does the variance decrease as you breed towards the selected target? because all phenotypes in the population are conserved because the distribution remains the same because the distribution of the phenotype decreases because the variability of the target phenotype increases Which cross would you perform in the sunflowers if your goal was to increase the variance of head size? cross sunflowers with large head sizes cross sunflowers with the most phenotypic variance cross sunflowers with small head sizes

Answer 1

Answer:

The correct answer is -

a. -because the distribution of the phenotype decreases

b. -cross sunflowers with the most phenotypic variance

Explanation:

Artificial selection is the process of the breeding plant or animal to develop a selective or desired phenotype character in a particular plant or animal by selecting which individual plants or animals sexually reproduce.

-Variance can be understood by the difference of individual from general characters of the species or deviation from the mean, which suggests how different the measurements.

-If the distribution or dispersion remains the same the variance shows no change so if the dispersion shows a change or different range of the measurements, change in the variance also takes place.

Answer 2

The correct answer is -

a. because the distribution of the phenotype decreases

b. cross sunflowers with the most phenotypic variance

The following information should be considered:

• Artificial selection refers to the process of the breeding plant or animal for creating a selective character in a particular plant or animal.
• In the case when the distribution remains the same the variance so it represent no change.
