Question
Chapter 36, Problem 10TYU
Summary Introduction
To explain:
How to determine if an organism can self-fertilize if it lacks
Concept introduction:
Self-fertilization is a process of sexual reproduction in which the fusion happens between the egg and sperm of the same individual. For this to happen, the organism has to be a hermaphrodite. Hermaphrodites are organisms who possess both male and female reproductive organs.

How does the fertilization envelope form in sea urchins?What is its function?arrow_forwardThe hymenopterans have a method of sex determination called ____, which is a type of meiotic parthenogenesis in which a fertilized egg develops into a female and an unfertilized egg develops into a male. This system is based on a single gene called the ____ gene (you may abbreviate the name of the gene). If an individual is heterozygous for this gene, it results in the production of female-specific mRNA from the second gene called the ____ gene, which in turn results in female-specific mRNA from a third gene called the ____ gene, resulting in a genetic cascade that causes the development of a female (you may abbreviate the gene names)arrow_forward

One of the distinguishing characteristics of mammals is their mammary glands, which allow for the production of milk. Even the more primitive mammals, such as the duck-billed platypus and the kangaroo, have some type of mammary glands. However, only the placental mammals (e.g. humans, horses, dogs) have a placenta, which supports the internal development of the embryo. The most primitive mammals have no placenta and can’t support the internal development of the embryo. Describe one function of the placenta found in mammals such as humans, horses, and dogs.arrow_forward

- Comparison Explain the comparison between the reproductive systems of the pig and frog. How does copulation differ between the two taxa? How does embryo formation compare, as it relates to the internal organs of the mother?arrow_forwardConsider the variation in reproductive systems within the animal kingdom. These are discussed in the textbook readings. Select 1 or 2 traits and compare and contrast the human situation with other members of the animals kingdom. Two examples of traits are sexual reproduction and menopause. Part B Describe the development of the human embryo from the formation of the zygote to the point where the three embryonic germ layers develop. List the types of adult tissues that are derived from each of these germ layers. Be prepared to discuss how disruption early in development can cause major problems in the body of the developing individual.arrow_forwardWhat is a likely evolutionary advantage of sexual reproduction over asexual reproduction? a. Sexual reproduction involves fewer steps. b. There is a lower chance of using up the resources in a given environment. c. Sexual reproduction results in variation in the offspring. d. Sexual reproduction is more cost-effective.arrow_forward
