Answer:
It is almost impossible to totally eliminate recessive alleles from a population, because if the dominant phenotype is what is selected for, both AA and Aa individuals have that phenotype. Individuals with normal phenotypes but disease-causing recessive alleles are called carriers.
Explanation:
While harmful recessive alleles will be selected against, it's almost impossible for them to completely disappear from a gene pool. That's because natural selection can only 'see' the phenotype, not the genotype. Recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools.
Answer:
Based on the context clues, the character feels sad.
Explanation:
A context clue can be defined as a piece of information given by the author that can help the reader understand something.
In the excerpt we are studying here, it is possible to find some information that leads us to believe the character is sad. If the author had only described the girl staring out the window at the other children playing a game, we wouldn't be able to conclude enough. She could be tired, sad... She could even be excited about it.
The author, however, tells us she's asking herself if she will ever play with them and how they can be friends. If she is watching the other kids while feeling left out, she is most likely sad. The other options do not seem to match these context clues.
