You are studying a population of American robins, Turdus migratorius, in which approximately 2% of all individuals carry a reces

sive allele for leucistic (unusually white) coloration. The population suddenly expands when an influx of robins arrives during spring migration, and the frequency of the leucistic allele drops to only 1.5%. Next season the frequency is still 1.5%. Does it appear that evolution occurred in the robin population in your study area?

Yes, It seems that evolution has occurred in this area.

Explanation:

Evolution refers to a phenomena in which new traits or alleles that favor a better survival of organisms in a given environment, become fixed in the population.

Evolution is characterized by appearance of new characters and change in allele frequencies.

In the given situation we find that the frequency of the recessive allele in the population has changed over time and the percentage has become fixed.

So, we can say that evolution has occurred in the robin population

Don marquis thinks abortion is almost always wrong because (most) fetuses loose a bright and valuable future.

<h3>What is Abortion?</h3>

The term "abortion" refers to the removal or evacuation of an embryo or fetus in order to end a pregnancy. Miscarriages, also known as "spontaneous abortions," are abortions that take place naturally and happen in 30% to 40% of pregnancies. An induced abortion, or less frequently "induced miscarriage," is when pregnancy is intentionally ended. Abortion, when used without modification, typically refers to an induced abortion.

Induced abortion is one of the safest medical treatments when performed correctly. The probability of maternal death in the US is 14 times lower following an induced abortion than following childbirth. Unsafe abortions—those carried out by practitioners without the required training or in circumstances with insufficient resources.
