Why do some females copy the mating decisions of others?Mate-choice copying benefits females by allowing them to avoid the costs associated with assessing potential mates, including time, energy, the risk of predation, and other sacrifices (e.g., Andersson, 1994; Pomiankowski, 1987; Reynolds and Gross, 1990; Wade and Pruett-Jones, 1990).擇偶條件測驗
What are the five factors influencing mate selection?Both women and men say they want a mate who is kind, understand- ing, dependable, sociable, stable, and intelligent. Personality traits such as these have made their way onto more stmctured instmments designed to assess mate preferences (Buss & Bames, 1986; Hill, 1945; McGinnis, 1958), but not in a systematic fashion.
Do most animals choose their mates randomly?Even without the intervention of farmers, most animals select mates carefully--they do not mate randomly. Charles Darwin noted this fact in his 1871 book Descent of Man and Selection in Relation to Sex. He suggested that mate selection is a powerful force of evolution similar in its effect to natural selection.
Is inbreeding nonrandom mating?Nonrandom mating can occur in two forms, with different consequences. One form of nonrandom mating is inbreeding, which occurs when individuals with similar genotypes are more likely to mate with each other rather than with individuals with different genotypes.
How unique am I genetically?It's often said that humans are 99.9% identical. and what makes us unique is a measly 0.1% of our genome.
What is random mating and non-random mating?Nonrandom mating occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. When the probability is the same, then individuals are just as likely to mate with distant relatives as with close relatives -- this is random mating.
What are the 5 principles of natural selection?Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.pat pat膏好用
How does non-random mating affect heterozygosity?That is an interesting result: non-random mating, even in the most extreme form of self- fertilization, has no effect on allele frequency. Selfing causes genotype frequencies to change as the frequency of homozygotes increases and the frequency of heterozygotes decreases, but the allele frequency remains constant.人情利是封邊到買
What are two examples of non-random mating?(1) Assortative mating: mating between individuals with similar phenotypes or among individuals that occur in a particular location. (2) Inbreeding: mating between related individuals.
