I’m pretty sure is the 3rd one
Answer:
Hey! The answer is B
Explanation:
Cell walls only belong to plants, and chloroplasts also only belong to plants. Besides that everything else belongs to both, and that means that B is the only right answer
Adaptation
The idea of "survival of the fittest" applies here. The phenotypes of the organisms the survive are the ones that get passed on to future generations while those of organisms who die off do not pass their phenotypes. Only the phenotypes that are better suited to the environment get passed on and, therefore, occurs more frequently in their populations.
Biotic and Abiotic factors differ greatly. A biotic factor is any living thing in an ecosystem, such as plants and animals. An abiotic factor is all nonliving things in an ecosystem, such as water, dirt, and rocks.
Answer:
From the observation, It can be seen that the bent-winged genotype is dominant, while the straight-winged genotype is recessive. Also, for the eye colour, the traits are found on only the X chromosome. This causes the males to inherit their eye colour from their mother, since females are the source of the single X chromosomes in males (XY- male). However, the females inherit their eye colour from their father's X-chromosome. Thus, it can be determined that the eye colour, in this instance, has a cross gender mode of inheritance due to its placement on the X-chromosome.
Parent phenotype
Take: Bent-wing (B), Straight wing (s), Red eye (R) Yellow eye (Y)
Prime generation parent
Female (Straight-wing, Yellow eye)- s s Y (ss- homozygous recessive trait)
Male (Bent-wing, Red eye)- B s R (Bs- Heterozygous dominant trait)
1st generation Parent (F1)
Female (Bent-wing, Red eye)- B s R
Male (Bent-wing, Yellow eye)- B s Y
