What is GENE?
A part of DNA that encodes for a particular characteristics
A part of DNA that determine all of our characteristics
The chromosome
The chromatid
Which one is correct about Gene and Allele?
Tall is a gene, while allele is the letter that represent the gene (tall)
Height is a gene, while allele is the letter that represent the gene (height)
Short is a gene, while allele is the letter that is used to describe the gene (short)
Based on the diagram, how many genes are on the pair of chromosome?
8

fully expressed in the phenotype of a heterozygote
partially expressed in the phenotype of heterozygote
partially expressed in the phenotype of homozygote

Choose the correct statement about genotype and phenotype
phenotype is the characteristics, while genotype is the genetic constituents that determine the phenotype.
genotype is the characteristics, while phenotype is the genetic constituents that determine the genotype
A test cross is ..
A cross between organisms of the same generation
A cross between an organism of recessive phenotype and another organism of dominant phenotype but of unknown genotype
A cross between an organism of dominant phenotype and another organism of dominant phenotype but of unknown genotype.
Considering tall plant is dominant over dwarf plant. To determine the genotype of a tall plant, we should cross the plant with:
a tall plant of different species
a tall plant of the same species
a dwarf plant of different species
a dwarf plant of the same species
In a test cross between a tall plant and a dwarf plant, how do we determine that the genotype of the unknown plant is heterozygous?
if all of the offspring is tall
if most of the offspring is tall
if half of the offspring is tall
if all of the offspring is dwarf
A true breed is..
an organism that produces offspring of the same variety generation over generation, with homozygous genotype
an organism that produces offspring of the same variety generation over generation, with heterozygous genotype
an organism with homozygous dominant genotype only
Mendel's experiment on Pea plant focused on which type of characteristics? (choose 3)
flower colour
height of plant
length of pea pod
Pea pod's colour
Choose inferences derived from Mendel's experiment of pea plant:
Each characteristic is determined by factors that exist in pair
The pair is separated during the moitosis
One factor is inherited from male parent and the other one is from female parent
Based on the diagram, determine the genotype of the parent plants
Tt x Tt
Tt x tt
TT x tt
TT x Tt
Mendel's First Law is...
The law of independent Assortment
The law of segregation
The two alleles for a heritable character separate into different gamete. This is a statement of which Mendelian's law?
Mendel's first law
Mendel's second law
