Describe an example of a sex linked trait in humans. Two different species mate and produce a zygote. As it starts to develop, it dies due to the genetic differences. What would this be called? How is the genetic determination of sex established in humans? Is the ...
Influences the genetic makeup but is not an observable trait itself. Although not visible, his alleles include one for each brown and blue eye color. 4 Trait Manifests as the result of multiple genetic interactions. His height is a trait influenced by various genes inherited from both parents...
Female mimicry is commonly considered in the context of alternative mating tactics as mimics can avoid male–male competition to gain increased access to females. We describe a case where one of the benefits to being a female mimic could be the increase in size of a sexually selected trait tha...
A trait is any distinguishing feature that is present in a living organism. Traits are often passed on from the parents to the offspring. Traits, however, change due to external environmental influences. The genes responsible for a particular trait are referred to as the genotype, and the ...
Hurling is an Irish variation of hockey Mutation A change in the nucleotide sequence of the genome of an organism or virus, sometimes resulting in the appearance of a new character or trait not found in the parental type. Variation The act, fact, or process of varying. Mutation The process...
A test of three possible hypotheses. Studies on Neotropical Fauna and Environment. 42: 225-33.Brede, E. G., J. Adis, and P. Schmeider. 2007. What is responsible for the var- iance in life history traits of a South American semi-aquatic grasshopper (Cornops aquaticum)? A test of ...
What is the principle behind homologous recombination, and what can it be used for in the laboratory? What environmental factors will make a population have more genetic variation? What is the interdisciplinary field that studies biological processes called?
Furthermore, if an animal expresses a personality, not all of its behaviours seem to contribute to a personality trait; for example, simple feeding behaviour may be irrelevant to boldness. Nevertheless, it is far from clear which conditions must be fulfilled for an animal to be assigned a ...

Understanding genetic variation has a particular benefit in the agricultural world, where trait selection in plants and livestock has been used for centuries to increase yield and quality. While traditional selective breeding involved purely observation...
