Citation: Student gives possible explanation for female mating preferences that decrease male survival chances (2019, June 6) retrieved 18 August 2019 from https://phys.org/news/2019-06-student-explanation-female-decrease-male.html Having an STI could benefit male animals Pavitra Muralidhar, a Ph.D. student in the Department of Organismic and Evolutionary Biology at Harvard University, has developed a theory to explain why females of some species are more attracted to some males who have a lesser chance of survival. In her paper published in the journal Nature, she outlines her theory of selfish sex chromosomes and how it might work in nature. Mark Kirkpatrick, with the University of Texas has published a News and Views piece in the same journal issue, outlining the work done by Muralidhar. This document is subject to copyright.

Journal information: Nature More information: Pavitra Muralidhar. Mating preferences of selfish sex chromosomes, Nature (2019). DOI: 10.1038/s41586-019-1271-7 Explore further © 2019 Science X Network Prior research has shown that females of some species are more attracted to males who posses certain impressive features, such as bright plumage. But such research has also shown that males who sport brighter plumage are more likely to be seen and eaten by a predator—so why do the females prefer them? Scientists have been unable to answer this question. But Kirkpatrick notes that there are two main theories. The first is called direct selection, and it is what it sounds like—genes that affect mating preferences are direct targets of selection. An example might be a male that is good at helping tend a nest, and is therefore highly prized by females looking for a mate. The other theory, quite naturally, is called indirect selection, and it involves females choosing mates who have one trait, but get another trait as part of the deal. A female who chooses a male based on plumage, for example, might wind up with a male that also has a good immune system, which is responsible for his great plumage. Unfortunately, neither of these theories explains why a female would go for a male that is clearly less likely to survive; doing so will decrease her male offspring’s chances of survival. Muralidhar suggests this phenomenon is due to what she describes as “selfish sex chromosomes.”Muralidhar’s theory is based on the indirect selection theory, and also sexually antagonistic selection, in which a gene benefits one gender, but could mean harm to the other. She also considers the possibility of an exception in situations where one gender has a pair of same chromosomes and the other has two that are different. She suggests that in cases in which a gene involved in mating is located on the chromosome that is present in only one gender, it can result in only offspring of the same gender carrying that gene, which could benefit them, but it could also bring harm to the offspring of the other gender. She has also carried out a mathematical analysis of her ideas to prove her theory and carried out a study of 36 species, half of which aligned with her “selfish sex chromosome” hypothesis expectations.

Jindal Steel and Power Ltd (JSPL) on Wednesday commissioned the country’s largest billet caster plant at Angul in Odisha.The billet caster plant, which would cast molten steel into semis of various sizes and shapes, would help the company to produce various long products used in construction sector. “We have commissioned India’s largest capacity billet caster plant in Angul within a record time of one year; setting yet another benchmark in the country,” JSPL’s Managing Director and Group CEO Ravi Uppal said in a statement.JSPL has a 2.5 mtpa steel making capacity at Angul and the company plans to raise it to six mtpa.Commissioning of the billet caster plant would enable JSPL to produce long products in addition to flat products already produced at the Angul plant.
People who have high incomes are more likely to be “weekend warriors,” exercising intensely just few days a week and spending most of their time in sedentary pursuits. Previous research has shown that higher income individuals are more likely to be physically active at a higher intensity.However, the research has historically relied on self- reporting, which may exaggerate actual activity levels.Income has been shown to be a prominent barrier to engaging in physical activity. Also Read – Add new books to your shelfResearchers from the University of Texas and Georgia State University in the US used activity monitors to collect data for the study published in the journal Preventive Medicine.Individuals with low incomes face time constraints as well as other barriers, including lack of exercise facilities, parks and open space, as well as an inflexible work environment, and have been shown to be less likely to meet physical activity guidelines.Meanwhile, higher income individuals who often also have limited time, have more resources and places to exercise, which could facilitate their ability to meet activity guidelines. However, they also are more likely to hold sedentary jobs, like office work.

It is important to remember, however, that we should increase the duration and intensity of activity gradually to avoid injury,” he said.”Also, if inactive consult with a physician before embarking on an exercise programme,” he added.
