Question
Chapter 43.4, Problem 1TC
Summary Introduction
To explain:
If the development in humans were as thoroughly determined as it is in sea squirts, would identical twins be more or less common.
Introduction:
Fertilization is a process in which haploid male gamete (sperm) fuses with the haploid female gamete (egg or ovum) that result in the formation of diploid zygote. The zygote then further develops into a blastula, gastrula that later results in the formation of an embryo.

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
