Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

The pathway for arginine biosynthesis in Neurosporacrassa involves several enzymes that produce a seriesof intermediates.ARG-E ARG-F ARG-G ARG-HN-acetylornithine → ornithine → citrulline → argininosuccinate → argininea.

A mitochondrial transfer technique may offer a potential solution for women with mtDNA-based diseases to have healthy children.This technique works by replacing the damaged mitochondria in the mother’s egg with healthy mitochondria from another woman’s donor egg. Based on what you know about the importance of nuclear gene products to mitochondrial functions, will this technique ensure that children will not inherit or develop a mtDNA-based diseases?

A human gene called the β-globin gene encodes a polypeptidethat functions as a subunit of the protein known as hemoglobin.Hemoglobin is found within red blood cells; it carries oxygen. Inhuman populations, the β-globin gene can be found as the common allele called the HbAallele, and it can also be found as theHbSallele. Individuals who have two copies of the HbSallele havethe disease called sickle cell disease. Are the following examplesdescriptions of genetics at the molecular, cellular, organism, orpopulation level?A. The HbSallele encodes a polypeptide that functions slightlydifferently from the polypeptide encoded by the HbAallele.B. If an individual has two copies of the HbSallele, that person’sred blood cells take on a sickle shape.C.

The cytochrome P450 system metabolizes many medicinally useful drugs. Although all human beings have the same number of P450 genes, individual polymorphisms exist that alter the specificity and efficiency of the proteins encoded by the genes. How could knowledge of individual polymorphisms be useful clinically?
In humans, the glucose-6-phosphate dehydrogenase (G6PD) gene involved in sugar metabolismis X-linked. The dominant allele (G) codes for fast enzymes for normal cell functioning while the recessiveallele (g) codes for slow enzymes, which are responsible for the reduced enzymatic activity of cells.However, the presence of slow enzymes has minimal effect in the overall functioning of heterozygotes,thus normal. Recessives, however, are more prone to oxidative reactions that speed up the celldamaging process, thus weak (but not lethal). If random inactivation occurs during dosage compensation,what would be the genotypes and phenotypes of the children of a heterozygous mother and a recessivefather?

The 13-Mb genome of the green alga Ostreococcus tauri contains ∼8000 genes. Compare the gene density in this eukaryote to that of E. coli (∼4300 genes) and that of A. thaliana (∼25,500 genes).
Ch. 13-7 Mutations in the TYR gene may render its enzyme product—tyrosinase—nonfunctional.Individuals homozygous for such mutations cannot make the pigment melanin. Albinism, the absence of melanin, results. Humans and many other organisms can have this phenotype (right). Mutated tyrosinase alleles are recessive when paired with the normal allele in heterozygous individuals.In the following situations, what are the probable genotypes of the father, the mother, and their children?a. Both parents have normal phenotypes; some of their children have the albino phenotype and others are unaffected.b. Both parents and children have the albino phenotype.c. The mother and three children are unaffected; the father and one child have the albino phenotype.
