Summary Introduction

To explain:

The term “endosperm”.

Introduction:

Double fertilization is a type of fertilization that occurs in angiosperms (flowering plants). In this process, the female gametophyte joins with two male nuclei. Two fertilization take place simultaneously in this process and thus, it is called double fertilization.

Summary Introduction

To determine:

The cell of the female gametophyte from which endosperm is derived.

Summary Introduction

To determine:

Whether endosperm is more abundant in mature seed of dicot or of monocot.

Introduction:

A seed is defined as an embryonic plant, which is enclosed within a protective covering (seed coat). New plants germinate from the seeds and thus, seeds are an essential part of the reproductive process of plants.  Plants that produce seeds are called phanerogams. A seed can either be a monocot or a dicot on the basis of the presence of cotyledons.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
