Answer:
The question is incomplete, it lacks the main questions, those questions are:
a. What is the genotype for black chickens?
b. What is the genotype for white chickens?
c. What is the genotype for erminette chickens?
Explanation:
This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.
The answer to the question presented above would be 'require frequent rainfall'. A plant native to the chaparral would be expected to require frequent rainfall. This is because it cannot survive in dry lands and without constant water.
The location where a crime occur is called a crime scene. There are two types of crime scene, primary and secondary crime scenes. The primary crime scene refers to the place where the crime actually takes place. The secondary crime scene is to some extent related to the crime but it is not the original place of occurrence of the crime.
In the question given above, the primary crime scene is the lockers' room, where the thief took the car's key from. Information about the identity of the thief, such as finger prints can be obtained at the primary crime scene.
The magnification of the ocular lens of a microscope is x10 and the magnification of the objective lens for low, medium, and high power are 4X, 10X, and 40X, respectively. The measured dFOV under medium power is 2.6mm.
