Ans:- Sexual Reproduction avoids the transmission of harmful Alleles to offspring.
As acording to the principles of Inheritance (Principle of Diminence , Indepandent Assortment , Segregation) expriments are perform that sugest that Transmission of harmful alleles are avoided during Sexual reproduction . Its one of the resion is that most of the harmful alleles are recessive , which do not experses itself in progeny.
1 Sexual reproduction increases genetic diversity, because of meiosis and involvment of two genetically different gamets
2 In Sexual Reproduction Pure lines are diluted, due to meiosis.
3 Sexual reproduction involves meiosis and fertilization which decreases chances that all the characterstics of offspring comes from one of the parent.

Which is NOT an advantage of asexual reproduction? Asexual reproduction allows rapid reproduction and population increases. Asexual reproduction can occur despite low population density. Asexual reproduction increases genetic diversity within the population. Asexual reproduction does not involve finding a mate.

According to an idea called the Red Queen hypothesis, sexual reproduction is favored over asexual reproduction when pathogens are present because it increases genetic diversity, allowing some of the host offspring to escape the pathogen. Some researchers were interested in testing this idea in aphids which can reproduce both asexually and sexually. In this study, the researchers measured rates of fungal infection and frequency of sexual reproduction across many populations to see if these two variables were related. It was...

my assigned organism is Naked mole rat (Heterocephalus glaber). please type it. The first step in understanding how information is passed from one generation to the next is understanding how cells divide, particularly how the DNA is passed on to the resulting cells. In this discussion, you will describe the life cycle of an animal or plant of your choosing. The animal or plant you choose must have a sexual life cycle (although it may also have an asexual life...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
