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.

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_forwardIs this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c.

Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phasearrow_forward
