Given a uniform environment the extent to which trait variation can be attributed to differing genes is called?
Heritability
Difference between broad sense heritability and narrow sense heritability?
Broad sense heritability A.K.A (H) is the degree in which phenotypic variation is due to genetic factors Narrow sense heritability A.K.A (h) is the degree in which phenotypic variation is due to additive genetic factors. in maths terms... H = Vg/Vt h = Va/Vt Vg= genetic varaition Vt = total variation Va = additive variation
What is the ability-of trait to be passed down from one generation to the next called?
It's called heritability.
What is the ability of a trait to be passed down from one generation to the next called?
It's called heritability.
Is it true that Mendel's law of independent assortment states alleles for different traits are passed on from one generation to the next independently of each other?
The Law of Independent Assortment. Which actually only applies if the examined traits are not linked to the same locus.
Given a uniform environment the extent to which trait variation can be attributed to differing genes is called?
Heritability
What genetic characteristics come from the bull?
Half the genes a calf gets is from his sire, and the other half from his dam. Some genes will be more dominant than others, depending on which of his parents has the dominant gene, and some, like carcass characteristics from his sire, are more heritable than others. Often a bull that has better genetics than the rest of the cowherd will produce calves that have slightly better genetics than their dams. Some of the more heritable traits that a bull's offspring can receive from him, if he's better quality than the cowherd, are: Lean/bone ratio (60% heritability) Lean percentage (55% heritability) Mature cow weight (50% heritability) Carcass grade (45% heritability) Thickness of outside carcass fat (45% heritability) Dressing percentage (40% heritability) Marbling (40% heritability) Ribeye area (40% heritability) Yearling weight (feedlot)(40% heritability) Yearling weight (pasture (35% heritability) Efficiency of gain (35% heritability) Birth weight (30% heritability) Post-weaning gain (30% heritability) Tenderness (meat quality) (30% heritability) Carcass weight (25% heritability) Weaning weight (25% heritability) Calf survival (10% heritability) Calving interval (10% heritability) Calving ease (10% heritability) The definition of heritability is: "The proportion of the differences among cattle, measured or observed, that is transmitted to the offspring. Heritability varies from 0 to 1. The higher the heritability of a trait, the more accurately does the individual performance predict breeding value and the more rapid should be the response due to selection for that trait."
Correlation refers to the extent to which two variables?
Correlation refers to the extent to which two variables relate to one another. This is often referred to in scientific studies.
What is the maximum value for heritability?
Heritablility values range from 0-1 so the maximum value of heritability would be 1.
What does to what extent mean in a sentence?
To what extent refers to how much does the subject of the sentence impact the current task. Example To what extent was the damage to the bridge when the car hit it.
The current estimate of heritability of intelligence is?
90
What are the strengths and weaknesses of some of the methods used to determine heritability in humans?
Heritability is the amount of variance in observed demeanors among people that can be explicated by genetics.
What would contribute to an overestimation of heritability?
One of manyÊthings that could contribute to incorrect or overestimation of heritability would be the infuence of environment factors including geographical location.
What is the estimated influence of genes on a trait called?
heritability
Which personality trait refers to the extent to which a persons likes to be with other people?
extroversion
What is latitudinal extent?
Latitudinal extent refers to angular distance. It's in degrees south or north to the equator and is equal to the angle at the center of the globe.
The likelihood of a trait being passed of from parent to offspring?
heritability.
