All of the black-footed ferrets alive today descended from just 18 individuals Why do you think this might be of particular concern to the species survival?
The black footed ferret captive breeding program has produced many kits; however, problems associated with inbreeding may develop. There are only 7 genetic founders represented in the breeding pool. Genetic analysis initially recommended maintaining 200 breeding animals in captivity to maintain 80% of the genetic diversity of founders for over 200 years (Ballou & Oakleaf 1989); this was later increased to 240 adults. To increase the productive capacity of breeding animals, captive management strives to maintain a ratio of 3 males:5 females. Emphasis is placed on genetic management of the captive population because of the comparative ease of managing its genetics relative to wild populations (Russell et al. 1994), and because mortality of reintroduced animals is high. Therefore, only genetically "surplus" animals (i.e., high inbreeding coefficients and high representation in the captive population) and numbers produced in excess of those needed to replace loss of captive animals are available for reintroduction (Godbey & Biggins 1994). Genetic studies to determine relatedness of "founders" were called for in 1985 but never conducted and ferret lineages remain estimates based on the locations of animals captured from the wild. In addition, animals of disputed paternity entered the breeding population in 1987-88. As a result, genetic management has been compromised.

What did cro-magnons achieve?
Survival. They never died out. Modern Europeans are descended from the Cro-Magnon.
What consists of all individuals of a particular species or particular place?
The term that refers to all individuals of a particular species in a specific place is called a "population." A population encompasses all members of that species living in a defined geographic area at a given time. It is a key concept in ecology and biology, as it helps in studying the dynamics of species, their interactions with the environment, and factors affecting their survival and reproduction.
What is the survival rate for individuals with trisomy 3 disorder?
averge survival has improved to age 50
What individuals had the greatest chance of survival in a death camp?
the guards.
What is meant by heterozygous advantage?
Heterozygous advantage refers to a situation where individuals with two different alleles for a particular trait have a survival or reproductive advantage over individuals that are homozygous for either allele. This advantage can result in genetic diversity within a population, which can be beneficial for the population's ability to adapt to changing environments.
In most populations the individuals that produce the greatest number of offspring are?
In most populations, the individuals that produce the greatest number of offspring are those that have traits advantageous for survival and reproduction within their environment. This can include traits like physical strength, disease resistance, or attractiveness to potential mates. Ultimately, natural selection favors individuals that are best adapted to their particular ecological niche.
What are the survival relationship in a community?
IN the case of a HUMAN community, more money earned and higher quality of life the higher the survival rates for the occupants of that particular community.
Why do plants produce lots of seeds?
In order to secure the and survival rate of next generation of that particular plant.
What theory is survival of the fittest?
Be careful with this, it is usually misinterpreted as survival of fittest individuals. Instead it is survival of fittest population via death of some individuals early. Individuals never evolve, they are fixed genetic snapshots in the movie of life, they simply live or die. Populations evolve.
Describe the three inferences Darwin made from his observations that led him to propose natural?
1. Production of more individuals than the environment can support will lead to a struggle among the individuals in a population resulting in the survival of a few. 2. Survival of the individuals will depend on inherited traits that will enhance their survival and reproduction. Those with traits that increase the probability of surviving will have a higher rate of survival and are likely to have more offspring than those who are less fit. 3. The ability of individuals to adapt to the environment will lead to a gradual change of the population retaining characteristics that accrue over generations source: Biology by Campbell and Reece
What does it meant to compete for living space?
Competing for living space refers to the struggle or conflict between individuals or groups over access to or control of a particular area or environment where they can reside or thrive. This competition can involve various factors such as resources, territory, or opportunities for growth and survival.
How can mutation lead to evolution in a population?
Mutation introduces variation in the genetic material of individuals within a population. This variation can result in different traits that may provide a survival advantage in a particular environment. Over time, individuals with beneficial mutations are more likely to survive and reproduce, passing on these advantageous traits to their offspring, ultimately leading to evolutionary change in the population.
