Many birds are monogamous, meaning that one male and one female mate for an entire breeding season. other animals are naturally polygamous, meaning one female has the opportunity to mate with many males or one male mates with multiple females. do you think monogamy and polygamy are reproductive strategies? in terms of species survival, what are the advantages and disadvantages of each method?

Monogamy in birds can be defined as a situation in which male and female parents live together for an entire breeding season, and neither of them change their partner. This is a characteristic feature in birds. Polygamy can be defined as a situation in which male and female parents live together for a particular breeding season, and they usually change their partner.

Yes, monogamy and polygamy are reproductive strategies followed by birds and mammals.

Advantages of monogamy

1. Monogamy involves the strategy in which both parents cooperate in rearing of the young ones. Thus, it results in the increase in the chances of survival of the offsprings.

2. Their is no competition for acquiring mates for copulation, hence can increase the chances of survival of members of population.

Disadvantages of monogamy

The absence of genetic variation makes the offsprings unfit for survival in the changing abrupt environmental conditions, hence can decrease the chances of survival of living organisms of species.

Advantages of polygamy

This will promote more genetic variations, hence allows the species to adapt according to the changes occurring in the environment, hence can increase the chances of survival of the species.

Disadvantage of polygamy

It results in the competition to acquire mates during breeding seasons. The members can fight or kill each other for mates, hence can decrease the members in the population.

Monogamous birds only have 1 partner.

Advantage: Both parents can take care of the kids with no fight.

Disadvantage: If 1 of the 2 dies the kids will be left with only 1 parent.

Polygamous animals have many partners.

Advantage: They can get help from each other at some point.

Disadvantage: They will come across fights on who is better.

Explanation:

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
