~Hello there! ^_^
Your question: Which nerve branches from the semicircular canals, and runs through the cochlea, and transmits sound and equilibrium?
Your answer: Vestibulocochlear nerve is the nerve branch that if from the semicircular canals, and run through the cochlea, and then transmits sounds and equilibrium.
Hope this helps~
Answer:
2. The gene responsible for eye color is on the X chromosome.
Explanation:
<em>For X-linked genes, a male can either be affected or unaffected because the Y chromosome is hypothesized not to carry any gene. Females on the other hand can be a carrier, affected or unaffected because the two sex chromosomes carry genes.</em>
If eye color allele in drosophilia is represented by R, the cross between F1 red-eyed heterozygous female and red-eyed males can be illustrated below:
Red-eyed heterozygous female =
Red-eyed male =
x
Progeny:
Out of the 2 male progeny from the cross, 1 () is white-eyed while the remaining one () is red-eyed
Hence, the result shows that the gene for eye color in Drosophilia is X-linked.
Option 2 is the correct answer.
Answer: Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
