Genetics

Question 1

is a branch of biology that studies hereditary information. It
deals with the mechanisms of heredity.

Answer 1

Genetics

Question 2

– refers to the passing of characteristics (ex. Eye color, height,
texture of hair, shape of earlobes, and skin color) from parents to offspring.
These characteristics are called hereditary because they can be passed on
from one generation to another.

Answer 2

heredity

Question 3

▪Is a portion of DNA that determines a
characteristic.

Answer 3

gene

Question 4

stores and passes on genetic information from one generation to another.

Answer 4

Deoxyribonucleic acid (DNA)

Question 5

It reviews the basic
laws of inheritance
that were described
by Gregor Mendel.

Answer 5

Mendelian genetics

Question 5

It deals with the
chemical nature of
the gene, the
mechanisms
transmission, and its
varied application

Answer 5

Molecular genetics

Question 5

He used garden peas to illustrate the mechanisms of heredity.

Answer 5

GREGOR JOHANN MENDEL (1822-1884)

Question 6

responsible for trait (purple or
white flower)

Answer 12

alleles

Question 13

the observable expressions
of the trait

Answer 13

allele that is expressed and masked the other allele
when both are present

Answer 14

dominant allele

Question 15

allele that is masked and not expressed when both
alleles are present

Answer 15

Question 17

refers to the offspring resulting from the parental
cross

Answer 17

filial generation

Question 17

factors affecting heredity includes

Answer 17

rule of unit factors in pairs
* principle of dominance and recessiveness
* law of segregation
* law of independent assortment

Question 18

which are sets of genetic laws
and rules that explain the factors affecting heredity.

Answer 18

medelian postulat

Question 19

when an organism has
two different alleles for a given trait, the allele
that is expressed, overshadowing the expression
of the other allele, is said to be dominant.

Answer 19

law of dominance

Question 20

describes the behavior of
the chromosomes during meiosis.

Answer 20

law of segregation

Question 21

this
states that the alleles of different genes
separate independently from each other
during gamete formation.
