Homologous genes that arise from
Step by step
Solved in 3 steps
- Some species reproduce asexually (they do not undergo meiosis). What consequences do you think this will have for genetic diversity across the genes of those speciesProteins that share significant amino acid similarity are called ______. ________ are related proteins from different species that likely to do the same function. ________ are similar proteins that arise by duplication events within the same species. paralogs; orthologs; homologs orthologs; homologs; paralogs homologs; orthologs; paralogs orthologs; paralogs; homologsThe ancestor of cats was presumably homozygous for wild type at all of the described genes. 1a. What was the genotype of this ancestral cat at each of these loci? Tyrosinase Orange Browning Dense Piebald Tabby Unstriped White-mask or
- Can you answer all the parts to this diagram Species 1 and 2 are sister species from which you’ve cloned related genes. On the gene tree on the top of the next page, use labels to answer the following questions: (a) Label the node that represents a gene duplication with “D,” (b) Label the nodes that represent speciation events with “S,” (c) Pick a pair of genes that are paralogs and label them both “P.” (d) Pick a pair of genes that are orthologs and label them both “O.”Genetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection. Explain or give an example.The number of haploinsufficient genes in humans is estimated to be about _______?
- Fill the blank New genes can arise during evolution through: (i) exonshuffling, which can alter the domain structure of proteins;(ii) duplication and divergence that generates gene families;and (iii)_______ mutations in intergenic DNA sequences.Meaningful evolution occurs when __________. ○ a heritable trait affects survival and fitness ○ a heritable changed trait gives an organism a fitness advantage ○ a changed trait gives an organism a disadvantage ○ environmental factors changeONE OF THE ANSWER IS WRONG PLEASE HELP ME FIND THE RIGHT ANSWER Duplication of genes is an important evolutionary mechanism. As a result, many, cases are known in which a species has two or more identical genes. Suppose there are two genes - A and B - that specify production of the same enzyme. These two genes show autosomal recessive inheritance. An abnormal phenotype results only if an individual does not make any of that enzyme. Only one of these two genes needs to be functional in order to make the enzyme. What ratio of normal to abnormal progeny would result from a mating between two parents of genotype AaBb where A and B represent alleles that specify production of the enzyme, while a and b do not? Write your ratio like this - e.g 1:2 ratio - Suppose now there are three genes - A,B and C that specify production of this enzyme and again only one single functional allele is sufficient for a wild-type phenotype. How many of the possible phenotypes would be normal? Write your answer…
