Peppered moths often hide on white-colored birch trees because they are similarly colored. Which of the following environmental changes would lead to the enhanced survival of darker moths? A) Warm weather causes the birch trees to grow their leaves back early.

B) Birch trees become covered in black ash from nearby factories.

C) Heavy rainfall causes birch trees to grow taller than normal.

D) Disease kills off more than half of the birch tree population.

Answers

Answer 1
Answer:

The ash would help darker colored mothscamouflage on the bark. Therefore, option (B) is correct.

What is natural selection?

The process through which populations of living things adapt and evolve is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some respects. This variety indicates that some people have characteristics that are more environment-appropriate than others.

The peppered moth is a type of night-flying moth that lives in temperate regions. The majority of its occurrences are in the northern hemisphere, specifically in regions such as Asia, Europe, and North America. The evolution of the peppered moth is an illustration of population genetics and natural selection in action.

Black ash from adjacent industriescoats birch trees. Ash would aidmoths with darker colours in hiding on the bark. As a result, choice (B) is the right one.

if a man is homozygous dominant for bent fifth finger and a woman is homozygous recessive. What is the probability that any offspring will have a bent fifth finger?

Answers

The probability that any offspring will have a bent fifth finger is 100% . All of their children will inherit one dominant allele from the man (B) and one recessive allele from the woman (b), resulting in the heterozygous genotype (Bb), which exhibits the dominant trait of a bent fifth finger.

Determining the probability of having offsprings with bent fingers

In a scenario where a man is homozygous dominant (BB) for a bent fifth finger trait, and a woman is homozygous recessive (bb) for the same trait, their offspring's probability of having a bent fifth finger can be determined.

Using a Punnett square, it's evident that all their offspring will inherit one dominant allele (B) from the man and one recessive allele (b) from the woman, resulting in a heterozygous genotype (Bb).

As the dominant allele (B) expresses the trait, the probability of any offspring having a bent fifth finger is 100% or 1, as all the children will exhibit this dominant trait.
