Yes, the two sex cells are usually a sperm (male) and an egg (female).
(Asexual reproduction is where there is no need for two organisms; Ex. Starfish, they lose an arm, it's arm regrows and the arm grows a body)

What is always true of sexual reproduction?
it is Offspring are the same as a single parents.
Do Nematodes reproduction?
both ways! it depends on the species. Some species are always sexual, and some species can do both.
Can Sexual reproduction produce many identical offspring?
No, sexual reproduction does not produce exact copies. Sexual reproduction is the combination of two different genetic codes, creating a completely unique life form. Asexual reproduction does produce exact copies.
Is the presence of large number of chromosomes in an organism a hindrance to sexual reproduction?
No. Sexual reproduction process does not depend upon the number of chromosomes in an organism. Chromosome numbers usually are expressed in sets. 2 sets of chromosomes are present in body cells of organisms. For example, human bears 23 pairs which means 46 numbers of chromosomes. The cells with 2 sets of chromosomes are called diploid cells (2n) and haploid cells contain only one set (n) of chromosomes. Gamete cells are always haploid which are obtained by meiosis cell division of diploid cells. In sexual reproduction fusion of two haploid gametes (male and female) results in formation of zygote which id diploid.So, the number of chromosomes present ina cell whether it is small (cat - 38 chromosomes) or large (butterfly- 380 chromosomes) does not affect sexual reproduction.
Offspring that result from reproduction can always maintain a parent's gene combinations?
edoptions. Novelstars answer is Asexual. Asexual reproduction bears offspring that always maintain a parent's gene combinations..
How is sexual reproduction similar in all species?
there is always sperm
What is always true of sexual reproduction?
it is Offspring are the same as a single parents.
Are male and female always required for reproduction to take place?
No they are only requiered in sexual reproduction, in asexual reproduction only one parent is needed.
Is both of sexual and asexual have genetic variations?
Yes, there will always be mutations.However, with sexual reproduction, there is a tendency for greater genetic variations.

What is an advantage of sexual reproduction over asexual reproduction?
Aside from fun, sex is good for introducing variability. Asexual, clonal, reproduction leads to exact copies of the parent. If the environment was always exactly the same, and if there were not pathogens trying to overcome the defenses of organisms, that might work out very well, and be very efficient. However, the creation of new combinations of genes that results from sexual reproduction results in novel forms, that may be more adapted to the unpredictable future, and may not be as susceptible to those pathogens that have come up with a way to attack other members of the species.
Why is sexual reproduction better than asexual reproduction for ensuring survival of a species in a changing environment?
Yes. Sexual reproduction is more advantageous than asexual reproduction in a challenging environment since sexual reproduction introduces more variation in the offspring. In asexual reproduction, the variation in offspring is caused by mutations and they are rare and a large number of offspring will have to be produced to ensure enough offspring with beneficial mutations are born, and this is not always possible when resources are scarce. In sexual reproduction, variation is introduced by recombination in addition to mutation, and recombination (random crossover of chromosomes) happens in every time the organism reproduces to introduce variation that may not be present in the parents. The greater amount of variation increases the chance of having offspring that are adapted to the challenging environment.
Which statement describes offspring produced by sexual reproduction?
A. It needs just one parent B. The offspring are always genetically identical. C. The offspring are not identical to the parents.

Does oogamy always involve fertilization from gametes of different sizes?
Yes, oogamy is a form of sexual reproduction where the female gamete is much larger than the male gamete.
When is the offspring in asexual reproduction not identical to the parent?
The offspring of a asexual organism will always be identical to the parent cell because it is never gaining new information like it would if it were sexual.
