The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.
The zebra fish is a very popular aquarium pet fish that is known to be hardy, attractive, and able to survive well in groups. Wild type zebra fish have blue–purple horizontal stripes that run from gill to tail, with a silver–gold body. An alternative form of the zebra fish results from a mutation that causes a homozygous recessive red-colour fish. Could you kindly answer all of the questions? It's multiple choice so minimal explanation is needed and i do not have a lot of questions left. Thank you. a) If 32 of 84 zebra fish have the recessive phenotype of red colour, what is the frequency of the recessive allele in this population of fish? a. 0.62 b. 0.38 c. 0.14 d. 0.79 b) What percentage of the population of zebra fish are heterozygous? a. 47% b. 38% c. 62% d. 53% c)How many zebra fish are purebreeding for the blue–purple horizontal stripes? a. 72 b. 12 c. 52 d. 5 d) If 15 years ago, 34 of 88 zebra fish had the red colour, has microevolution occurred? Why or why not?…
Organizations that aim to protect the rights of animals have been battling leisure breeders to stop selective breeding because they view it as a form of abuse or cruelty to animals. Selective breeding or artificial selection is a mechanism that has brought a huge impact on the gene frequency of animals especially domesticated ones like dogs and cats. There are cases when breeding animals such as dogs resulted in diseases and malformation or abnormalities in the resulting offspring. Is s it proper to continue selective breeding? Support your claim and your answer in a bulleted format. this is not a writing assignment
Select all examples of mutations that are likely to be dominant to wild-type alleles. Select all examples of mutations that are likely to be dominant to wild-type alleles. Check All That Apply An amorphic allele of Gene B when Gene B is haploinsufficient. A hypomorphic allele of Gene A that reduces its function by 75%, when one wild-type allele of Gene A is sufficient for a wild-type phenotype. A hypermorphic allele of Gene C that encodes a constitutively active protein. An antimorphic allele of Gene D that encodes a protein that forms homodimers. A neomorphic allele of Gene Ethat results in expression of a transcription factor in the wrong cell types.
How can mutations cause changes to the traits? Explain using the following steps:1- DNA 2- Gene 3- Protein 4- Traits We need one explanation for the normal side and one for the mutation side. Can you explain in a few sentences how the change in the structure of the gene affects the function of the corn plant?
Generally speaking, there are four types of mutations. Which of two of these four have the main effects on fitness? O beneficial O deleterious O lethal O neutral
The MC1R gene affects skin and hair color in humans.There are at least 13 polymorphisms of the gene inEuropean and Asian populations, 10 of which are nonsynonymous. In Africans, there are at least 5 polymorphisms of the gene, none of which are nonsynonymous.What might be one explanation for the differences inMC1R variation between Africans and non-Africans?
For a mutation that does not have a fitness cost to the individuals who carry it, we call the mutation a -synonymous mutation -beneficial mutation -dominant mutation -homologous mutation -neutral mutation
Which one of the following options most accurately describes the process that generates the signature of a selective sweep in DNA sequence data? suppression of mutation over a long haplotype centered on a positively selected allele genetic hitchhiking of neutral alleles flanking the favored allele at the nucleotide site under positive selection O higher than average recombination around the core allele under positive selection
What is the expected relationship of Dn and Ds for a gene under selection to maintain its current function? Dn > Ds Dn = Ds Dn
How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)
Albinism in humans can be caused by mutations in any one of several different genes. This situation, in which the same phenotype may result from variation in several different genes, is referred to as genetic heterogeneity. Is genetic heterogeneity common? Are most genetic traits in humans the result of variation in a single gene, or are there many genetic traits that result from variation in several genes, as albinism does?
