1. Which of the following is a direct example of phenotypic plasticity? The same tree producing different size fruit in different years , depending on the weather. Selecting trees over multiple generations for a mutation that produces larger fruit.
What is an example of phenotypic plasticity?
Phenotypic plasticity refers to the ability of a genotype to express different phenotypes depending on the environment in which it resides. For example, genetically identical water flea (Daphnia) clones can differ in their morphology depending on whether reared in the absence or presence of a potential predator.
What is phenotypic plasticity quizlet?
What is phenotypic plasticity? The ability of a genotype to produce distinct phenotypes when exposed to different environments throughout its ontogeny .
What do you mean by phenotypic plasticity?
Phenotypic plasticity can be defined as ‘ the ability of individual genotypes to produce different phenotypes when exposed to different environmental conditions ‘ (Pigliucci et al. 2006). ... As with any organismal trait, the way in which an individual responds to environmental influences is subject to evolutionary change.
What is an example of phenotypic?
Examples of phenotypes include height, wing length, and hair color . Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is plasticity explain with example?
In physics and materials science, plasticity is the ability of a solid material to undergo deformation , a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself.
What is phenotypic plasticity and why is it important?
Many organisms have the ability to express different phenotypes in response to environmental conditions. Such phenotypic plasticity allows individual organisms to develop appropriate morphological, physiological, or behavioral traits that better fit a particular environment that they encounter .
Which of the following is an example of phenotypic plasticity quizlet?
The depth of root growth in response to soil moisture is an example of phenotypic plasticity, a change in growth that occurs in response to environmental conditions.
Why is plasticity important for development quizlet?
Why is plasticity important for development? Because plasticity speeds up development . Because plasticity ensures that change happens at a rate that the individual can manage. Because without plasticity, it would be impossible to remember things.
When an organism moves from sun to shade it reduces heating by conduction?
True or False? When an organism moves from sun to shade, it reduces heating by conduction . True; reduces heat gain by conduction because the ground and every object around you is giving you heat, while everything around you in the shade is cooler.
Is phenotypic plasticity natural selection?
Main Text. Natural selection acts on phenotypes , yet evolution occurs at the level of genotypes. ... This suggests that plasticity may largely impede adaptive evolution. However, it has been posited that plasticity may facilitate or even promote adaptation in certain contexts.
Is PP genotype or phenotype?
A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP ( homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive).
Do humans have phenotypic plasticity?
Humans have been reported to exhibit phenotypic plasticity in sperm allocation depending on variation in socio-sexual situations.
What is a simple definition of phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type . The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What is difference between genotype and phenotype?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not . Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
