Mendel conducted experiments crossing pea plants that differed in distinct traits like seed color and shape. He discovered that traits are transmitted from parents to offspring through discrete units called genes located on chromosomes. His laws of heredity showed that for each trait there are two alleles that separate during gamete formation, with one randomly passed from each parent. The dominant allele will be expressed in offspring while the recessive is not. Additionally, different genes assort independently during gamete formation and fertilization.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
2. What is heredity?
The passing on of
characteristics (traits)
from parents to offspring
Genetics is the study of
heredity
3. Mendel used peas...
They reproduce sexually
They have two distinct,
male and female, sex cells
called gametes
Their traits are easy to
isolate
4. Mendel crossed them
Fertilization - the uniting
of male and female
gametes
Cross - combining gametes
from parents with
different traits
5. Questions
What did Mendel cross?
What are traits?
What are gametes?
What is fertilization?
What is heredity?
What is genetics?
6. What Did Mendel Find?
He discovered different
laws and rules that explain
factors affecting heredity.
7. Rule of Unit Factors
Each organism has two
alleles for each trait
– Alleles - different forms of
the same gene
– Genes - located on
chromosomes, they control
how an organism develops
8. Rule of Dominance
The trait that is observed
in the offspring is the
dominant trait (uppercase)
The trait that disappears
in the offspring is the
recessive trait (lowercase)
9. Law of Segregation
The two alleles for a trait
must separate when
gametes are formed
A parent randomly passes
only one allele for each
trait to each offspring
11. Questions...
How many alleles are there
for each trait?
What is an allele?
How many alleles does a
parent pass on to each
offspring for each trait
12. Questions...
What do we call the trait
that is observed?
What case (upper or lower)
is it written in?
What about the one that
disappears?
What case is it written in?
13. Phenotype & Genotype
Phenotype - the way an
organism looks
– red hair or brown hair
genotype - the gene
combination of an organism
– AA or Aa or aa
14. Heterozygous & Homozygous
Heterozygous - if the two
alleles for a trait are
different (Aa)
Homozygous - if the two
alleles for a trait are the
same (AA or aa)
15. Dihybrid vs Monohybrid
Dihybrid Cross - crossing
parents who differ in two
traits (AAEE with aaee)
Monohybrid Cross -
crossing parents who
differ in only one trait
(AA with aa)
16. Questions...
What is the phenotype?
What is the genotype?
What is homozygous?
What is heterozygous?
What is monohybrid
crossing?
