(a)
To determine: The meaning of maternal effect genes.
Introduction: Development of an organism at the cellular level is marked by the process of specification, differentiation, and development. Various genes are involved in the proper development of an embryo.
(b)
To determine: The period of development of gene products of maternal effect genes and their location.
Introduction: The development in Drosophila is maintained by the zygotic genes and maternal effect genes. Maternal effect genes regulate the early embryonic development in an organism.
(c)
To determine: The aspects of development that are controlled by maternal effect genes.
Introduction: As mentioned in the concept introduction part (b).
(d)
To determine: The
Introduction: Maternal effect genes are activated after the process of fertilization. These control the axis and polarity of an embryo.
