The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring. This could mean sexual vs. asexual reproduction .
What is a reproductive strategy?
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival.
What are some examples of reproductive strategies?
The female benefits by mating with a genetically fit male at the cost of having no male help care for the offspring. For example, in the yellow-rumped honeyguide (a bird) males defend beehives because the females feed on beewax. As the females approach to find beeswax, the male defending the nest will mate with them.
What are two main reproductive strategies?

What are 2 types of reproduction?
There are two types of reproduction: asexual and sexual reproduction . Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.
What actions is a reproductive strategy?
The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring . It could refer to things like sexual vs. asexual reproduction.
What is the goal of reproductive strategies?
What is the Ultimate goal of a species? Is to produce the maximum of surviving offspring while using the least amount of energy . What are the 2 kinds of fertilisation?
What is R vs K selection?
r-selected babies grow rapidly , and tend to be found in less competitive, low quality environments. ... K-selected species produce offspring that each have a higher probability of survival to maturity.
What is ultimate goal of reproductive strategies?
The overarching objective of the strategy is to accelerate progress towards meeting internationally agreed reproductive health targets and, ultimately, to attain the highest achievable standard of reproductive and sexual health for all.
What is meant by reproduction Class 8?
Reproduction is the process by which living organisms produce more living organisms of its own kind . It is very important as it ensures the continuation of similar kinds of individuals, generation after generation. Modes of Reproduction: There are two main types of reproduction in living organisms.
What is R and K reproductive strategy?
The terms r-selection and K-selection are used by ecologists to describe the growth and reproduction strategies of organisms. r-selected species have a high growth rate but low survivability (“cheap” offspring) K-selected species have a low growth rate but high survivability (“expensive” offspring)
What is meant by reproduction?
1 : the act or process of reproducing specifically : the process by which plants and animals give rise to offspring and which fundamentally consists of the segregation of a portion of the parental body by a sexual or an asexual process and its subsequent growth and differentiation into a new individual.
Do female apes approach the male?
There are at least five behavioral and physiological means by which female primates can potentially exert choice. During her receptive phase, a female can simply approach a male and make sure she is in close proximity. ... Females can also avoid certain males.
What are the reproductive strategies in fish?
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body . The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants. Some have adhesive eggs.
Are dogs r strategists?
Examples of r-strategist species are dogs , cats, insects, and fish.
