Why do you think asexual reproduction is more common in animals like flatworms and sponges than in vertebrates ?

What is evidence that menopause is an adaptive cooperative trait? In humans, the presence of reproductive (fertile) grandmothers probably increases the survival rate of their grandoffspring. O In killer whales, the presence of reproductive (fertile) grandmothers increases the survival rate of their grandoffspring. In both humans and killer whales, the presence of non-reproductive grandmothers probably increases the survival rate of their grandoffspring. In humans, the presence of reproductive (fertile) mothers increases the survival rate of their reproductive grandparents.

In asexual reproduction only ______  ______________is involved, and the offspring are genetically _____________________to the parent. – In Unchanging environments In sexual reproduction _______ _________________are involved, and the offspring are genetically ___________________from the parent. – Changing environments Evolution is _____________  _____________over time in a ________________________. Different organisms have different genes. How is it that so many organisms seem perfectly suited to their environment? ___________  _____   ___________________. After a genetic __________or mutation in an organism, It survives, reproduces, and passes along its genes. Beneficial ______________ develop at random. The environment “___________” beneficial adaptations. Adaptations are an inherited characteristic.

What are the three ways in which sexual reproduction enhances the degree of genetic variability among individuals?

What is inability to reproduce known as?

|(A) Humans have some rather unique features to our reproductive behavior. One strange one, relative to other animals, is female menopause. What might be the selective advantage to this feature? (B) What selective forces may have led to the evolution of menopause in humans?

Why do we still see organisms reproduce asexually? In what situations and organisms would we expect to see asexual reproduction occur?

Some organisms are capable of asexual or sexual reproduction. Under favorable conditions, reproduction proceeds asexually. When conditions become more stressful reproduction switches to a sexual mode. Why?   Question options:   Sexual reproduction is simple and more rapid allowing larger numbers of offspring to be produced.   Sexual reproduction requires two separate individuals, who can mutually provide nutrient support during stress.   Sexual reproduction produces individuals with new combinations of recombined chromosomes increasing diversity.   Asexual reproduction requires more energy.

how does sexual reproduction produce more complex offspring, produce a greater number of offspring, enhances the genetic variability, produce more evolutionary fit individual and Increases the survival rate of the species?

What Is autogamy ? Why it is not preferred in nature?
