Explain the difference between domestication and taming of animals

why are mutations in genes usually recessive?
with respect to what is stated above and from what you know about eukaryotic cells, their chromosomes, and genes. (How many chromosomes do we have, for example, and how many pairs? Think pairs.)

It is sometimes difficult to evaluate the risks posed by biotechnology because:

A. It is impossible to carry out large-scale trials for risk assessment
B. It is difficult to know how a genetically modified organism will interact with other organisms in its ecosystem and what the biological consequences will be
C. Animals cannot be used to test products that are designed for humans
D. The cost of risk assessment for most biotechnological products is too high
.Which of the following is an ethical concern related to genetically engineering human beings?

A. Increased socioeconomic problems
B. Torture of animals to reach this end
C. Potential human genetic homogeneity, leading to an increased chance of the species being wiped out
D. Increased environmental problems

Explain how homologous organs and
vestigial organs support speciation through
evolution.

If the original population of 200 (from question #1) was hit by a tsunami and 100 organisms were wiped out, leaving 63 homozygous recessive out of the 100 survivors. Assuming that all individuals were equally likely to be wiped out, how did the tsunami affect the predicted frequencies of the alleles in the population? (Hint: Assume the new population is at equilibrium – AFTER the event – so you are comparing two populations which are at equilibrium to look for changes in allele frequencies.)

If 15% of the population carries at least one copy of the recessive allele: What is the predicted frequency of individuals in the population that express the dominant phenotype? What is the predicted frequency of individuals in the population that express the recessive phenotype?
