Genetics
2/26/25
Learning intention:
We are learning about Mendelian genetics and the process it took to develop our
understanding of inheritance and segregation
Success criteria
I can explain how organisms get their unique characteristics
I can explain how different forms of a gene are distributed to offspring using the
law of segregation
● Trait: specific characteristic (e.g., seed color, plant height) of an individual
● Hybrid: created from a cross of true-breeding individuals
● Monk born in 1922 who carried out inheritance experiments in the monastery
gardens.
○ Started with “true breeding” plants- peas
○ True-breeding plants would produce the same set of traits in each
generation.
○ Crossed true-breeding individuals to produce hybrids.
● Pea plants can self-pollinate. This is asexual reproduction
● Genes are the things passed from one generation to the next determine
individuals characteristics
● Alleles the different forms of a gene
● An organism with one dominant allele will exhibit that trait
● An organism with a recessive allele will exhibit the trait only in the absence of a
dominant allele

LI
We are learning to make predictions about the expression of specific traits.
SC
I can define six vocabulary words, and then use them in a sentence.
I can explain from where an organism gets its unique characteristics.
I can explain how different forms of a gene (alleles) are distributed to offspring.
● PTC is phenylitocarbanime
● PTC can be tasted by some people but not others
● Humans have 46 chromosomes
● Genotype is the dominant and recessive alleles
, ● Phenotype is the trait being displayed
● Segregation is the separation of alleles during gamete formation
● Heterozygous means it has two dif alleles
● Homozygus has the same
LT
We are learning to make predictions about the expression of specific traits
SC
I can explain the relationships between dominant and recessive alleles
I can describe the difference between dominant and recessive alleles
I can demonstrate how the law of segregation works and able to explain the difference
between an allele and gene
● Probability is the likelihood an even will occur if you flip a coin each flip is an
independent event
● Genotype is genetic makeuo
● Phenotype is physical traits
● Two organisms can share the same phenotype but have different genotypes

We are learning to make predictions about the expression of specific traits
SC
I can explain how probability can be used to predict inherited traits.
I can explain the difference between a genotype and a phenotype.
I can explain how alleles segregate when more than one gene is involved.
I can identify Mendel’s contributions to our understanding of genetics.
● Homozygous: has two identical alleles for a gene
● Heterozygous: has two different alleles for a gene
● Independant assortment: Genes for different traits can segregate independently
during gamate formation
