Correct answer is (a) Metacentric

Correct answer is (c) Hypertrichosis

Correct answer is (d) centromere

Homologues are homologous chromosomes which are morphologically similar to each other.

The law of segregation of Mendelian genetics is universally applicable.

The law of independent assortment of Mendelian genetics is not universally applicable.

Correct answer is (c) colour

Punnett’s square is the alternative term for the checker board.

Correct answer is (b) euploidy

Correct answer is (a) primary constriction

(b) multilevel inheritance

(b) Private members of base class are not inherited to the derived class with private accessibility

(c) Constructor

The visibility mode in inheritance specify the access mode of base class members to derived class.

When a newly created class need to acquire properties of existing class and with its own properties then it is necessary to use inheritance.

Suppose X is a class exist and we need new class Y having all properties of X and in addition to its own, then we need to inherit X class to derive Y class.

Single inheritance:

A derived class with only one base class is called single inheritance. For example, If A is base class then class B derive from base class A.

It is a derived class with only one base class is called single inheritance.

The secondary constriction present on the chromatid arms of a chromosome is called nucleolar organizer.

A base class is a class from which other classes are derived.

class First():

def _init_ (self):

print “first”

class Second(object):

def_ init_(self):

print “second” class Third(First, Second):

def _init_ (self):

First._init_ (self)

Second._init_(self)

print “that’s it”

t=Third()

t=Third()

The inheritance is implemented using the following syntax class derived_classname : access specifier base classname.

The base class is declared as the virtual base class so that only one copy of its members are inherited by the derived class in a hybrid inheritance. For example, the derived class D derive from the classes B and C whereas both the classes B and C are derived from base class A. Then base class A is inherited twice and to avoid two copies of class A to class D, class A is declared virtual base class.

Type of inheritance: Multilevel

An abstract method is a method defined in a base class, but that may not provide any implementation. It is done by using the abc module in Python, import abc class Shape(object):

metaclass = abc.ABCMeta

@abc.abstractmethod

Inheritance is a mechanism in which a new class is derived from an already defined class. The derived class is known as a subclass or a child class. The preexisting class is known as base class or a parent class or a super class. The mechanism of inheritance gives rise to hierarchy in classes. The major purpose of inheriting a base class into one or more derived class is code reuse. The subclass inherits all the methods and properties of the super class.

Abstract class is one that is not used to create objects. An abstract class is designed only to act as a base class.

An abstract method is a method declared in a parent class, but not implemented in it. The implementation of such a method can be given in the derived class, class

Correct answer is (c) independent assortment

Correct answer is (b) Hbs

The gene which causes the death of the bearer is called lethal gene.

Correct answer is (c) Green seed

The two or more alternative forms of a given gene which are present on the identical loci on the homologous chromosomes are called alleles of each other.

The specific segment of DNA or sequence of nucleotides which is responsible for the inheritance and expression of that character is called a gene.

Hypertrichosis is Y linked gene which can be seen only in males, therefore it is called holandric gene

Correct answer is (c) 50 percent

The person having recessive gene for haemophilia is deficient in clotting factors (VIII or IX) in blood, such person’s blood does not clot and he thus becomes a patient of haemophilia.

Correct answer is (a) homozygous

Roans possess the mixture of red and white colour side by side due to codominant alleles for red and white traits.

Correct answer is (c) synapsis

Correct answer is (d) Down’s syndrome

(c) On the basis of the position of the centromere

When a character is controlled by two or more than two pairs of genes, the genes are called polygenes.

Correct answer is (a) an organism

Correct answer is (b) multiple alleles

Crossing over takes place in the homologous region of the chromosomes.

Correct answer is (d) 1 : 6 : 15 : 20 : 15 : 6 : 1
