Anyone in your class has all the same genetic traits that you have?
no they cant
Homologous chromosomes are similar in all of these characteristics EXCEPT?
carry the same alleles for all traits
What are the traits produced by an organisms genes?
All inherited traits are a product of the organism's genes.
What is the offspring of plants that all have the same traits of parents?
A pure-bred plant that is homozygous for the traits being transfered.Alternatively a plant that is produced asexually/ vegetatively through cloning
Do traits vary from person to person?
Yes! Many types of people can have many different traits. There are people who have similar traits, but not everyone can have the exact same set of personality or physical traits.
What determines Which traits will be passed on to the next generation?
trait dominance (genotypic relationship between alleles). look up "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."
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.
How does heritability affect natural selection?
Without the heritability of individual traits what difference would it make if the individual was selected. An individual that has a germ line mutation, say, and this mutation could confer survivability and reproductive success on progeny thus passes this mutation to said offspring is selected. Then evolution, the change in allele frequency over time in a population of organisms, could take place. Heritability is all as individuals are selected but populations evolve.
List the three conditions that are necessary and sufficient for natural selection to act on a?
A beneficial mutation leading to variability in a population and the heritability of those beneficial traits.
That anyone in the class has all the same traits that you have?
no they cant
What are the conditions of natural confitions?
Natural selection is a process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully, leading to evolutionary changes in populations over time. It results from variation in traits among individuals, heritability of those traits, and differential survival and reproduction based on those traits.
Anyone in your class has all the same genetic traits that you have?
no they cant
What is the maximum value for heritability?
Heritablility values range from 0-1 so the maximum value of heritability would be 1.
Why is it more difficult to estimate heritability in humans than in livestock or laboratory animals?
Heritability is the likelihood of different traits being passed down in a species. It is more difficult to estimate in humans than in livestock or laboratory animals because humans are less controlled. Humans will interbreed among races and cultures, while animals generally keep to their own type.
Homologous chromosomes are similar in all of these characteristics EXCEPT?
carry the same alleles for all traits
The current estimate of heritability of intelligence is?
90
