A gene is a hereditary trait in your body and also apart of your DNA not visible to the naked eye making up how you look
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Answer:
The correct answer is "C. Cave fish have evolved degenerated eyes because they have no use for vision in dark, underwater caves."
Explanation:
All of these statements about organism adaptation to its environment are true, but the real reason why cave-fish are blind is not because there's no use for their eyes in the dark, but because being blind saves them energy, as using one's vision requires the activity of photoreceptive cells and neurons, and underground caves are lacking in both food and oxygen.
A parasite moving between individuals other than parents and their offspring uses
horizontal transmission.
Horizontal transmission is the transmission of infections between (parasites) that are not in a parent-child relationship (vertical transmission). Horizontal transmission may include the carriers or <span>vectors which are other species. Transmission, in that case, occurs via the bite of the vector (an infected organism), like in malaria.</span>
The root cap??? I think not for sure though.
