There is a population of alien dogs, species Dogus Cute-ee-us, that live on the planet Woof. Their genomes and biology are amazi
kupik [55]

Answer:

c. 1:4:6:4:1

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.  

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.  

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. In the exposed example, the measurable trait is the dog´s friendliness. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

In the exposed example, each dominant allele contributes with a higher level of friendliness.    

  • aabb → 0 = Unfriendly/Loner (although not aggressive);
  • Aabb, aaBb → 1 = Somewhat friendly/shy;
  • AAbb, AaBb, aaBB → 2 = Friendly;
  • AABb, aABB → 3 = Very friendly;
  • AABB → 4 = Maximally friendly.

Parentals) AaBb    x    AaBb

Gametes) AB, Ab, aB, ab

Punnett square)   AB       Ab       aB       ab

                   AB   AABB   AABb  AaBB  AaBb

                    Ab   AABb    AAbb  AaBb  Aabb

                    aB   AaBB    AaBb   aaBB   aaBb

                    ab    AaBb    Aabb   aaBb   aabb

F1) 1/16 AABB ⇒ 4 = Maximally friendly

    4/16 AABb + AaBB ⇒ 3 = Very friendly

    6/16 AAbb + AaBb + aaBB ⇒ 2 = Friendly

    4/16 Aabb + aaBb ⇒ 1 = Somewhat friendly/shy

    1/16 aabb ⇒ 0 = Unfriendly/Loner

The Phenotypic ratio is 1:4:6:4:1

1. Which image represents the flow of a longshore current in relation to a sandy beach?​
Dimas [21]

Answer: Option C

Explanation:

When waves of water approach the beach, they do so as an angle because they have been slowed down by the first parts of the beach that they have encountered.

When they hit the beach at an angle, they come back to the water and keep doing so like the movement shown in option D. This constant motion moves the sand and other particles on the beach progressively and the current that does so is the Longshore current which <em>moves parallel</em> to the coastline.
