Thus, the correct answer is - neoteny.
Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.
Answer: Chaparral biome is made up majorly of infertile land and the climate of the biome is majorly hot and dry. Thus, the plant biodiversity in the biome is limited and some plants may not be available all the year through. Due to this fact, the animals living in the area have to survive by learning to eat whatever plant is available per season. If the animals are able to eat only one type of plant, they will suffer hunger and possibly death if that particular plant is no longer available. Therefore ability to eat different type of food is an adaptation for survival in the chaparral biome.
