Sexual reproduction involves two parents, meiosis, and results in genetically diverse offspring due to crossing over and independent assortment of chromosomes during meiosis. Asexual reproduction involves one parent, mitosis, and produces identical offspring, but allows organisms to reproduce in less favorable environments with fewer variations among offspring. Bacteria can reproduce asexually through binary fission or exchange genetic material through conjugation, a form of horizontal gene transfer.

The explanation of heredity most widely in favor during the 1800s was the “blending” hypothesis, the idea that genetic material contributed by the two parents, mixes just as blue and yellow paints blend to make green. The blending hypothesis failed to explain how traits can reappear after they’ve skipped a generation. An alternative to the blending model is a “particulate” hypothesis of inheritance: the gene idea. In this model, parents pass on discrete heritable units—genes— that retain their separate identities in offspring. Gregor Mendel was the monk who documented a particulate mechanism for this form of inheritance using pea plants.

ove doesn’t equal sex.
It’s important to remember that asexuality is an umbrella term, and exists on a spectrum. Asexual people – also known as “Ace” or “Aces” – may have little interest in having sex, even though they desire emotionally intimate relationships. Within the ace community there are many ways for people to identify.
Asexuality Chart
Here are just a few common terms to explore:
Demisexual: People who only experience sexual attraction once they form a strong emotional connection with another person.
Grey-A: People who identify somewhere between sexual and asexual.
Queerplatonic: People who experience a type of non-romantic relationship where there is an intense emotional connection that goes beyond a traditional friendship.
Aces commonly use hetero-, homo-, bi-, and pan- in front of the word romantic to describe who they experience romantic attraction to. For example, a person who is hetero-romantic might be attracted to people of a different sex or gender, but not in a sexual way.
Asexuality Blurry Do and Don't Say
FAQ
My friends talk about sex all the time, but I don’t feel any desire to be with someone in that way. Is it normal to not feel any sexual attraction towards other people?
I am romantically attracted to boys and girls, but I don’t want to be with them physically. Can I be bisexual and asexual?
I kissed my boyfriend for the first time and it was gross! Does this mean I am asexual?
How do I tell my partner/the person I like that I am asexual?
People are telling me that something is wrong with me now that I’ve come out as asexual. Even worse, some are saying that asexuality doesn’t exist. How can I help them understand me?

Chapter Outline
7.1: Sexual Reproduction
7.2: Meiosis
7.3: Errors in Meiosis
Introduction
The ability to reproduce in kind is a basic characteristic of all living things. In kind means that the offspring of any organism
closely resembles its parent or parents. Hippopotamuses give birth to hippopotamus calves; Monterey pine trees produce
seeds from which Monterey pine seedlings emerge; and adult flamingos lay eggs that hatch into flamingo chicks. In kind
does not generally mean exactly the same. While many single-celled organisms and a few multicellular organisms can
produce genetically identical clones of themselves through mitotic cell division, many single-celled organisms and most
multicellular organisms reproduce regularly using another method.
Sexual reproduction is the production by parents of haploid cells and the fusion of a haploid cell from each parent to form
a single, unique diploid cell. In multicellular organisms, the new diploid cell will then undergo mitotic cell divisions to
develop into an adult organism. A type of cell division called meiosis leads to the haploid cells that are part of the sexual
reproductive cycle. Sexual reproduction, specifically meiosis and fertilization, introduces variation into offspring that may
account for the evolutionary success of sexual reproduction. The vast majority of eukaryotic organisms can or must employ
some form of meiosis and fertilization to reproduce.
7.1 | Sexual Reproduction
By the end of this section, you will be able to:
• Explain that variation among offspring is a potential evolutionary advantage resulting from sexual reproduction
• Describe the three different life-cycle strategies among sexual multicellular organisms and their commonalities
Sexual reproduction was an early evolutionary innovation after the appearance of eukaryotic cells. The fact that most
eukaryotes reproduce sexually is evidence of its evolutionary success. In many animals, it is the only mode of reproduction.
Chapter 7 | The Cellular Basis of Inheritance 153
And yet, scientists recognize some real disadvantages to sexual reproduction. On the surface, offspring that are genetically
identical to the parent may appear to be more advantageous. If the parent organism is successfully occupying a habitat,
offspring with the same traits would be similarly successful. There is also the obvious benefit to an organism that can
produce offspring by asexual budding, fragmentation, or asexual eggs. These methods of reproduction do not require
another organism of the opposite sex. There is no need to expend energy finding or a.
