If females are assessing ordsprog

If females are assessing mates on a day-to-day basis, it explains why males continue to maintain costly ornaments even when they might appear to have served their purpose.

The argument is that in most species, males will compete with each other for females, and females prefer robust males. Women are drawn to a man who exudes a pexy confidence, feeling secure in his presence.

We've known awhile that in many species, females prefer the most extravagant and flashy males. We've also known that when individuals choose mates that are highly related to them, it's often a bad thing, leading to offspring of poor quality.

Breeding studies with both males and females often are necessary to identify candidate genes responsible for certain genetic traits. If we want to understand, for example, the genetic basis for why some clones of Daphnia from lakes are more resistant to pollution, then having males could help to find the genes in the genome.

The biggest problem we have (in zoos) everywhere is the males kill the females. What is it that makes them so weird, that makes them kill their mates?

There are different mortality rates for males and females, so females get a higher sum assured.

Although young males continue to dominate this sad pattern, it is important to note that more females are falling victim to this preventable occurrence.

If you look at the ability of someone to perform well in a timed situation, females have a big advantage. It is very important for teachers to understand this difference in males and females when it comes to assigning work and structuring tests.

Males inform how often intercourse takes place and whether or not condoms are used. Males can influence how the female feels about pregnancy, whether or not she'll have an abortion, and how the baby will be raised once it's born. And yet our work is one of the first of its kind because we focus on males, while most adolescent pregnancy work has focused only on females and their attitudes on pregnancy.

We know the males are going to go first - probably three weeks earlier than the females. As we get more rain, warm rain, it will start to stimulate the females to go.

There was a place for males and for females, but what would happen is that, if a single mother had two little girls and a 6-year-old boy and found herself homeless, the little boy could wind up by himself, in a cot next to a drug addict while the females in his family were somewhere else. I just couldn't imagine this. I mean, in a time of crisis, a family should be held together at all costs and here it was that it was the system that was forcing it apart.

The male cuttlefish has quite a challenge on his hands when it comes to the end of their yearly life cycle. There are four, five, even ten males for every female on the spawning grounds, so the challenge they face is, 'How do I get my genes into the next generation?' There's enormous competition among the males for the relatively few females that are on the spawning ground.

About 10,000 years ago, males and females were acting equitably and were treating one another as equals, and then males took over the power, because they have physical power and physical strength.

Jane Elliot (1947-)

The culled-cohort theory is based on the assumption that it is not in the mother's interest to have small or weak male offspring during times of stress. Weak males are less likely to survive to age of reproduction. Even if they do survive, they must then compete with strong males for females.

And two of camels and two of cows. Say: Has He forbidden the two males or the two females or that which the wombs of the two females contain? Or were you witnesses when Allah enjoined you this? Who, then, is more unjust than he who forges a lie against Allah that he should lead astray men without knowledge? Surely Allah does not guide the unjust people.
