Data Interpretation Bar charts
Bar charts are a type of graph that are used to
display and compare the number, frequency or
other measure for different discrete categories
of data.
Bar charts are one of the most commonly
used types of graph because they are simple
to create and very easy to interpret. They are
also a flexible chart type and there are
several variations of the standard bar chart
including horizontal bar charts, grouped or
component charts, and stacked bar charts.
The chart is constructed such that the
lengths of the different bars are
proportional to the size of the category they
represent. The X-axis represents the
different categories and so has no scale. In
order to emphasis the fact that the
categories are discrete, a gap is left
between the bars on the X-axis. The Y-axis
does have a scale and this indicates the
units of measurement.
Directions (Q No. 1 – 5): Study the given
graph carefully to answer the questions that
follow.

In the last and concluding part of
the series of EAMCET model papers,
in the second year syllabus Unit-III ,
Unit-IV and Unit-V is being
discussed. All are of the related
topics dealing with classical and
molecular genetics. Some subsections of Molecular genetics are a
new addition to the old syllabus.
Both long term and regular students
feel difficult to understand these
chapters. Most of the question will be
knowledge based and easy questions.
Problems on DNA and genetics is a
regular feature in EAMCET exams.
One or two problems may be given
from these units. Practice is essential
for this type of questions to save time
on solving the questions. In
Biotechnology part of the syllabus
not more than one question can be
expected whereas in the application
part knowledge based questions can
be asked.

appearance of the offspring of
the cross TTGg x ttGg
1) All tall and green
2) All tall plants with green or
yellow flowers.

statement
regarding
codominance in Lens culinaris

shows both traits.
4) One fourth of F2 generation
shows both traits
In a population of true breeding
plants of Antirrhinum white
flowers are 144. The number of
red flowers is
