The highest and lowest percentage of male offspring per female parent at
Introduction:
Aphids are one of the pest insects that are responsible for damaging the crops. The species reproduce in response to photoperiodism. They produce wingless females giving birth to offspring in absence of male gamete in spring and summer and lay eggs only in winter.

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.
Include stages of reproduction in roaches - starting with the egg and sperm to zygote then to young offspring to adult( be sure to include the accurate number of chromosome)
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 eukaryotic organisms use sexual reproduction as their primary means of perpetuating their species. Gametes are formed via meiosis. However, some species primarily reproduce via asexual means. Reproduction is accomplished via mitosis. Aspen trees most commonly reproduce by such asexual methods of cloning.What are the advantages and disadvantages of reproduction by asexual means? Why do some species reproduce in this manner? Why don't all species?arrow_forwardAt the end of mitosis in Aedes aegypti, each of the daughter cells will have chromosomes; however, at the end of meiosis, each daughter cell will end up with chromosomes.arrow_forwardThe diagram below illustrates the lifecycle of the parasite - Toxoplasma gondii. This single celled organism causes the disease, Toxoplasmosis, which can be transferred to humans when cleaning out litter boxes.

- 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.arrow_forwardWhy 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.arrow_forwardFigure 9.3 Schematic representation of sexual reproduction (hyphal fusion) in Sordaria fimicola. ㅏ (a) Tan X Tan (b) -Haploid- Black X Black (c) Tan X Black (with no crassing-over) Fusion -Diploid- Majosis I 想想 * X* X * Y * X * Meiasis I X X X X X X -Haploid- Mitosis Position in ascus Bad D II CHIXO Nonrecombinant typearrow_forward
- If red vizcacha rats (Tympanoctomys barrerae) have 100 autosomes and 2 sex chromosomes in each of their diploid somatic cells, then they must have: only 102 chromosomes in their haploid germ cells only 100 chromosomes in their haploid germ cells only 52 chromosomes in their haploid germ cells only 51 chromosomes in their haploid germ cells only 50 chromosomes in their haploid germ cellsarrow_forwardWhen the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true? A. The trait for spore color is determined by exactly one gene. B. The trait for spore color is determined by more than one gene. C. The allele for black spores is dominant over that for white spores. D. The allele for white spores is dominant over that for black spores.arrow_forwardYou find two closely related species of fly, one (P) of which appears to reproduce parthenogenetically (a form of asexual reproduction) while the other (S) reproduces sexually. In the same location, I find a third kind of insect, a sterile defensive form with enlarged mandibles. Because it is sterile, I conclude this form must be produced by either P or S. Which do you think is most likely the producer of the sterile defensive individuals? Answer:arrow_forward
