The life of sex

Sex chromosomes influence physical differences between male and female animals, such as feather patterns in mandarin ducks. In most animals, sex chromosomes help determine whether an individual develops as a male or female. Sexes of some animals, such as most male arachnids, lack a second sex chromosome entirely. These chromosomes contribute to the physical differences between males and females. Birds with ZZ sex chromosomes, for example, are male and tend to be more colorful, whereas ZWs are females with typically blander plumage. Researchers hypothesize that animals with mismatched sex chromosomes, such as XY male mammals, could be more vulnerable to genetic mutations, which could result in a shorter life span. So researchers at the University of New South Wales, Sydney, scoured scientific papers, books, and online databases for sex chromosome and longevity data. They compared the life spans of males and females of animal species across 99 families, 38 orders, and eight classes. On average, the sex with identical chromosomes lives The longevity pattern holds for humans, wild animals, and captive animals across the evolutionary family tree.

By Joshua Rhett Miller. March 6, pm Updated March 6, pm. A Texas woman who used the trendy slang term as her nickname on the streets has been sentenced to life behind bars for forcing a year-old runaway into prostitution, according to a report. She had faced anywhere from five to 99 years or life in prison, the newspaper reports. Her conduct is representative of a person who never again needs to see a free day. She had previously turned down a deal by prosecutors to plead guilty to sexual assault of a child in exchange for a year prison sentence. Investigators said Dooley posted escort services ads for the teen on skipthegames. The jury also heard from a year-old man, who testified that he was 10 or 11 years old when Dooley sexually assaulted him at her apartment in Hooks, Texas, according to the Texarkana Gazette.
