3. Question?
⢠Are they difference?
⢠What is the differences between them?
⢠Do they have any similiar characteristic ?
⢠Where do they get all these characteristics?
5. What color is the parent?
What is the characteristic of the first filial?
What is the characteristic of the second filial?
What is the propotion between the color?
3 yellow : 1 green
6.
7. State
⢠The color of parent flower
⢠The color of offspring flower
⢠Where the color goes?
8. State:
⢠What is obvious color of the flower?
⢠purple
⢠Predict the color of offspring flowers
⢠Purple and white
9. What
⢠Trait can be observe?
⢠Cant be seen in one generation?
⢠Less color in the offspring?
⢠What is the name of the trait that can be seen
regularly
⢠What is the name the trait that seldom be seen
⢠What factor controling the trait??
10. ⢠Trait always can be seen = dominance trait
⢠Trait seldom be seen = recessive trait
⢠Dominance trait is control by dominance factor
⢠Recessive trait is control by recessive factors
⢠The factor is called gene
11. Gene and alelle
⢠Every trait is control by a gene
⢠Gene consist of two allele
⢠Each allele is located at a chromosome
U
1 chromosome
1 allele
12. Gene dan allele
Trait â control by a pair of allele at homolog
chromosome
What is homolog chromosome?
Homolog chromosomes pairsChromosomes in the
cell
13. Gene dan allele
TT
Homolog chromosomes
AlleleAllele
Gene consist of
2 allele in same
Location at
homolog chromosomes
14. ⢠The yellow color bean is control by dominance
gene (K)
⢠= KK
⢠The green color bean is control by ressesive
gene (k)
⢠= kk
⢠Heterozygote form: = Kk
⢠The color is yellow, yellow is dominance
15. KK
Yellow parent X Green parent

18. What is..
⢠Parent genotype ?
⢠Parent Phenotype ?
⢠Genotype F1
⢠Phenotype F1
⢠Genotype F2
⢠Phenotype F2
⢠Phenotype ??? Genotype ???
19. ⢠Genotype = type of allele that
control the trait
⢠Phenotype = the characteristic can
be seen
20. So:-
⢠KK = pure breed (homozygote) - yellow
⢠Kk = hybrid (heterozygote) - yellow
⢠kk = pure breed (homozygote) â green
⢠Practice:
â Do the cross of the following:
22. What is the conclusion can be
made?
⢠Trait is control by a pair of allele, only
an allele can be inherited in gamete.
First Mendel Law
(Law of Segregation)
any pair of characteristics there is only one gene
in a gamete even though there are two genes in
ordinary cells.
25. Two trait inherited.
Each trait is controlled control by
two allele
Each of the allele from any trait
able to combine during gamete
formation in meiosis .
27. Key:
U â dominance allele for purple eye
U â recessive allele for red eye
H- dominance allele for black body
H â recessive allele for brown body
Draw schematic diagram to show the inheritance of the trait in F1
and F2 generation.
