What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
What are the advantages and disadvantages of outbreeding?
Advantages: Outbreeding often produces offspring of superior quality because it increases homozygosity (the occurrence of two alleles for the same trait at corresponding positions on homologous chromosomes), thereby sharply reducing the risk of deleterious recessive genes being expressed. Crossbreeding is the most common form of outbreeding.
What cell organelles are most closely associated with energy changes in a plant?
the chloroplast and the mitochondria are the organnels closely related to energy production in plants
What are two types of selective breeding and how are they compared?
Two types of selective breeding are inbreeding and outbreeding. Inbreeding involves mating closely related individuals, increasing the chance of inheriting both desirable and undesirable traits. Outbreeding, on the other hand, involves mating unrelated individuals, which can increase genetic diversity and reduce the prevalence of genetic disorders.
What is the difference between cross breeding and inbreeding?
Cross breeding involves mating two unrelated individuals from different breeds or populations to produce offspring with a mix of traits. Inbreeding involves mating individuals that are closely related, such as siblings or parent-offspring, which can lead to an increase in genetic defects or expression of negative traits due to the lack of genetic variation.
What is the difference between inbreeding and interbreeding?
Interbreeding most commonly refers to breeding two different species within the same genus to get a hybrid. An example of this is breeding a male donkey and a female horse to get a mule.Inbreeding refers to the breeding of two organisms who are related to one another.
How are selective breeding techniques of hybridization and inbreeding opposite?
In hybridization, individuals from different breeds or varieties are crossed to produce offspring with desired traits, promoting genetic diversity. In contrast, inbreeding involves mating closely related individuals to increase the frequency of desired traits, which can lead to a decrease in genetic diversity and an increased risk of inherited genetic disorders.
What are the two methods of selective breeding?
The two methods of selective breeding are inbreeding, where closely related individuals are bred to emphasize particular traits, and outbreeding, where unrelated individuals are bred to introduce new genetic variability.
What are the two kinds of reproductive isolation mechanisms that biologists divide?
Temporal isolation-species mating at different times of the year.Behavioral isolation-mating behaviors in two groups of isolated populations change, thus making individuals from the two groups not attracted to each other.Pollinator isolation-some closely related plant species have flowers that attract different pollinators, preventing the two species from inbreeding.Mechanical isolation-when reproductive organs in closely related species change drastically, making it impossible for one species to mate with another.Gametic isolation-when incompatibilities between the sperm and eggs of closely related species keep them from fusing.Hybrid inviability or sterility-when the egg gets fertilized, the resulting offspring may not live (inviable) or it is sterile.
Can different kinds of bears mate?
no because all bears are almost the same except if there different color Some can. For example, there are known cases of polar/brown bear hybrids. These two are closely related species.
Which two species are most closely related to each other?
Humans and chimpanzees are the two species that are most closely related to each other.
Which two species are most closely related in terms of genetic similarity?
Humans and chimpanzees are the two species that are most closely related in terms of genetic similarity.
What is the difference between hybridization and inbreeding?
Hybridization crosses dissimilar individuals to have offspring with the best of both (Trial and Error), and Inbreeding crosses organisms that have similar characteristics (same type) - Pure Breeds
What is used to tell if two organisms are related?
Same genus or closely related species.
Is a polar bear a Kodiak bear?
No, but the two are closely related.
