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.

In C. elegans there are two sexes: hermaphrodite and male. Sex is determined by the ratio of X chromosomes to haploid sets of autosomes (X/A). An X/A ratio of 1.0 produces a hermaphrodite (XX), and an X/A ratio of 0.5 results in a male (XO). In the 1970s, Jonathan Hodgkin and Sydney Brenner carried out genetic screens to identify mutations in three genes that result in either XX males (tra-1, tra-2) or XO hermaphrodites (her-1). Double-mutant strains were constructed to assess for epistatic interactions between the genes (see table). Propose a genetic model of how the her and tra genes control sex determination.
What is the proposed evolutionary benefit of sexual reproduction?
Why is parthenogenesis in bees considered to be a form of asexual reproduction? Select one: a. The male drone is made from a haploid egg. Fertilization is not part of the process to make a male drone. b. The formation of the original haploid cell was achieved using binary fission. c. Although genetic material is transferred from one cell to another using conjugation, the resulting cells will be identical to each other. d. The haploid male bees were made through the process of meiosis, so they are identical to the parent egg cell.

For keyboard navigation, use the up/down arrow keys to select an answer a Production of eges and sperm in separate sexes in an animal species b. Gradual acquisition of multiple mutations in a purely mitotically dividing eukaryotic single celled organism Occasional production of diploids through fusions of cells of opposite mating types in a yeast that largely reproduces through clonal mitotic divisions "Alteration of generations" between haploid and diploid organisms in a fern
One reason that worker bees forgo their own reproduction to help their sister (the queen) reproduce is that female bees are more closely related to their sisters than they are to their own offspring. This quirk of genetics results from the fact that bees have haplodiploid sex determination, in which females are diploid, with a mother and a father, but males are haploid, developing from unfertilized eggs. Because males are haploid, they produce sperm by mitosis. Explainwhy haplodiploid sex determination causes females to be more closely related to their sisters than to their offspring.
Most species reproduce sexually. Some species are entirely asexual, while others can reproduce in both modalities. a) Why is asexual reproduction so rare? b) What can we learn about the factors that maintain sexual reproduction from studying species that can reproduce both sexually and asexually?
One of the advantages of sexual reproduction is that it promotes genetic diversity in the offspring. This is because gametes are produced by meiosis, which introduces genetic variation into the resulting gametes. How does meiosis accomplish this? Describe one way (there are several choices) in which meiosis produces new combinations of genes in gametes.
Why do we still see organisms reproduce asexually? In what situations and organisms would we expect to see asexual reproduction occur?

Binary fission is a form of asexual reproduction. What is an advantage of asexual reproduction when compared to sexual reproduction? a Asexual organisms are less likely to have mutations in their DNA than sexual organisms are. b An organism that reproduces asexually can reproduce much more quickly than an organism that reproduces sexually. c An asexual organism lives longer than an organism that reproduces sexually. d An organism that reproduces asexually is better equipped to respond to environmental changes than an organism that reproduces sexually.
Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages? A) Mitosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation. B) Meiosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation. C) Mitosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation. D) Meiosis must occur at some point in the life cycle to prevent a reduction of chromosomes in each generation.
