A difference in an inherited trait of an organism that may lead to new species?
variation
Difference between adaptation and natural selection?
Adaptation are the physical or the behavioral traits that make an organism better fits to its environment while the Variation usually comes from random mutations. Mutations are iniatially cause by a new heritable traits.
How do you xxplain how the hitchhicker's thumb trait is determined using the following words allele domnate recessive homozygous heterozygous?
basically, the hitchhiker's thumb is a physical characteristic that is inherited from your mother and/or father. when you were conceived, your mother gave you some of her genes, and your father gave you some of his. the hitchhiker's thumb is either a dominent or recessive trait. It if is dominant, you could have a heterozygous parent and still have a 100% chance of inheriting it. If the hitchhiker's thumb is recessive, you must have both of you parents homozygous for the gene to have a 100% chance of inheriting it. The alleles are either HH (homozygous dominant), Hh (heterozygous), or hh (homozygous recessive). H H << if the thumb is dominant trait, you have a 100% chance of getting it H HH HH << if the thumb is recessive trait, you have a 0% chance of getting it h Hh Hh
What are the 4 factors of natural selection?
1. All populations have genetic variation 2. The environment presents challenges to successful reproduction 3. Individuals tend to produce more offspring than the environment can support 4. Individuals that are better able to cope with the challenges presented by their environment tend to leave more offspring than those individuals less suited to the environment doIndividuals better able to adapt to changes leave more offspring.
A trait that is hidden?
The trait that is hidden is recessive trait.
A variety of a trait improves an organism's survival enabling it to produce more offspring than other members of the population then the trait is said to be what?
it is said to be fit
What is the definition of selective advantage and how does it contribute to the survival and evolution of species?
Selective advantage refers to a trait or characteristic that gives an organism a better chance of surviving and reproducing in its environment. This advantage allows the organism to pass on its genes to the next generation, leading to the evolution of the species over time. In essence, selective advantage plays a crucial role in the survival and adaptation of species by favoring traits that increase an organism's chances of thriving in its specific environment.
What does a mutation help with?
mutation help increase our chance of survival. By giving an non-existing gene or trait to an individual of a species population. This special gene can either be passed on or extinct. The special gene will pass on if the gene have proven it is useful and will extinct if its not. Overall, mutation help all life survival in the ever-changing environment and challenge they face.
What is the central force in evolution?
There is no central force, except that anything which does not hinder a gene's chance of reproducing will allow whatever species that gene belongs to live on. If a trait helps a species to survive, that trait will be "selected". Look at it this way, if a particular trait means that some members of a species is less likely to breed than other members, that trait will die out eventually. This could mean that lions which have shorter claws than their fellows, or cheetahs which can't run as fast as their fellows will go hungry, and be less successful in having and rearing cubs which carry their genes. That is not so much a force driving evolution as a force culling those members of a species which are "less fit" for survival than their fellows
What describes adaptations?
A trait that is beneficial to survival.
What is known as adaptation?
A trait that is beneficial to survival.
How does indirect selection play a role in the evolution of species?
Indirect selection in evolution occurs when a trait that is not directly related to survival or reproduction becomes advantageous due to its association with other beneficial traits. This can lead to the spread of the trait through a population over time, ultimately contributing to the evolution of a species.
What would the offspring most likely be if an individual with a heterozygous trait and an individual with a homozgous recessive trait crossed be?
The offspring would have a 50% chance of being heterozygous and showing the dominant trait and a 50% chance of being homozygous for the recessive trait.
What explains why innate behavior is shared by members of the same species?
Innate behaviors are genetically programmed and passed down through generations within a species. They provide a survival advantage or aid in reproduction, so individuals within the same species share these behaviors to increase their chances of survival and successful reproduction. This shared trait enhances the overall fitness of the species.
What is an inherited characteristic that increases an organism's chance of survival.?
Adaptation c==3
How do changes at the DNA and gene level change populations to eventually form new species?
I think you're talking about genetic mutation... If the trait is dominant then it will be spread to its offspring and if it doesn't hinder the offspring's survival then the trait will continue to be passed on to new generations.
Traits that improve the chance for survival?
It can be almost anything: a trait that allows an individual to run quicker, to hide better, to metabolize food better, to defend better against diseases, etc.
