In any scientific paper you can find th eprocedure part which should in detail explain how the procedure of a particular experiment was performed. Using these instructions we should be able to replicate an experiment, if the results that were obtained in the previoues experiments were correct of course.
Answer:
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
Explanation:
In laborador retrievers, pigment color is influenced by two genes. Gene A determines the type of pigment produced and gene B affects whether the pigment gets deposited in the hair shaft. If two heterozygous black laborator retrievers were crossed and offspring were produced in a ratio of 9 black dogs to 3 brown dogs to 4 yellow dogs, what are the genotypes of the offspring?
Gene A determines colored pigment.
Gene B ensures that the colored pigment is deposited.
Two heterozygous black laborador retrievers were crossed.
AaBb x AaBb
Progeny
9 A_B_
3 A_bb
3 aaB_
1 aabb
<em>Since there were 9 black, 3 brown and 4 yellow dogs, the possible genotype of the different colors are: </em>
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
The answer is moss.
Mosses are nonvascular seedless plants. <span>Nonvascular plants have simple tissues specialized for internal water transport.</span>
On the other side, vascular plants have vascular tissue which consists of xylem and phloem. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.
