Answer:
- The Island population likely has fewer alleles-that is versions of genes-than the mainland population.
A- Agree <u>B- Disagree</u>
- Genetic drift is more pronounced in the island population than in the mainland population in these first few generations
A- Agree <u>B- Disagree</u>
- Some harmful traits may have become more common in the island population than in the mainland population
<u>A- Agree</u>- B- Disagree
- Biologist observed genetic drift but not evolution
<u>A- Agree</u> B- Disagree
Explanation:
If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.
Answer:
1
Explanation:
Lichen are usually the first thing to grow on bare rock, making them a pioneer species. Fun fact, you can use lichen to determine if the air quality in an ecosystem is polluted.
Hope this helped :)
involves the loss of all part of a chromosome or one base
answer: Deletion
Answer:
C) the three-base sequence of mRNA
Explanation:
Three-base sequence of mRNA is called codon. One codon specifies a single amino acid. There are 64 codons in eukaryotic cells and three of them are stop codons (non-coding).
tRNA have three-base sequence called anticodon which is complementary to specific codon. During the process of translation codon and anticodon are paired which leads to addition of amino acid to growing polypeptide chain. Newly added amino acid is carried by tRNA.
