Answer:
Statements are missing. These are,
1-Consumers may reduce exposure to these by washing and peeling fruits and vegetables.
2-These may be used to increase weight gain and meat production in cattle.
3-These include organophosphates and sex pheromones.
4-Golden rice is yellow because it contains beta-carotene, which the plant can now manufacture because genes for certain enzymes were inserted in the rice genome.
5-Their use may be avoided in favor of integrated pest management (IPM).
6-Scientists inserted the Bt gene into corn to make it resistant to the corn borer.
7-These include recombinant bovine somatotropin (rbS

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
Natural selection, random genetic drift, mutation, population mating structure, and culture.
