The muscles in the leg are considered long muscles. As the muscles in the leg contract and relax they work to provide movement.
Maurinko [17]

Answer: if the upper leg muscles were damaged, (You would not be able to extend the leg straight).

Explanation:

The upper leg muscles, which can also be called the thigh, are made up of three sets of muscles which include:

--> the hamstring muscles: These are located at the BACK of the thigh. They are made up of three long muscles which includes the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle.

--> the quadriceps muscles: They are located at the FRONT of the thigh. They consists of four individual muscles which includes the three vastus muscles and the rectus femoris.

--> the adductor muscles: They are located at the medial compartment of the thigh and is consist of the following muscles: gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.

The quadriceps, hamstrings and adductor muscles work together to straighten (extend) and bend (flex) the leg. Therefore when there is damage to the upper leg muscles, you would not be able to extend the leg straight.

In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is
Agata [3.3K]

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.
