What is genetics?

Why did Gregor Mendel experiment with garden peas?

Why was Gregor Mendel's work with garden peas significant?

Which 7 pairs of characteristics did Gregor Mendel observe in his study of garden peas?

Before beginning his experiments, Mendel bred out pea plants for each characteristics over several generations. Why did he do this?

How did Mendel conduct his experiment with the pure bred pea plants?

What were Mendel's conclusions on how characteristics are inherited, after his experiment with the pea plants?

In Mendel's experiment, the experimental ratios were 3:1. Account for this.

What two laws did Mendel develop from his experiments with the garden pea plants?

Explain Mendel's Law of Segregation

Explain Mendel's Law of Independent Assortment

Outline reasons why Gregor Mendel was successful, in terms of his experimental techniques.

Summarise the 5 reasons why Gregor Mendel was successful in terms of his experimental techniques

How long did Gregor Mendel collect data for with how many plants and when was Gregor Mendel's work recognised?

Why was Gregor Mendel's work not recognised until much later, after his publication?

How was Mendel's work recognised?

What are monohybrid crosses used for?
Monohybrid crosses: involves looking at one characteristic only.

What is genotype?

What is a phenotype?

In a phenotype, for each characteristics, at the least--what is the number of factors which control it?

When gametes form, a pair of factors (genes) segregate. What does this mean for the factors that will be in the gamete?

The gene that is passed on is randomly selected during meiosis and is randomly united with one of its _____ during fertilisation to form a ______.

What is a zygote?

In alleles, one allele is ______ over the other which is _______.

If both alleles are the same, they form what type of a genotype?

If both alleles are different, what genotype do they form?

Hence, how does genotype affect phenotype?

What are genes?

Genes occur in ____

Where are genes situated?

How is each gene expressed in a diagram of a chromosome?

How are genes passed on and what do they determine?

In a sexually reproducing organism, where does the offspring's genes come from?

In humans, how many chromosomes are there?

Two genes code for each factor on every pair of homologous chromosomes EXCEPT for?

Some genes have several alleles. Why is this?

What is an allele?

Some factors only have 2 genes and 2 varieties (alleles) however, others may have many different varieties = many different genes BUT only 2 can be inherited- one on each homologous chromosome.

Where do alleles occur?

Alleles make us ___

Provide an example of an allele and a gene/

Provide another example of a gene and an allele.

What are the 3 alleles of the gene of blood type.

Explain the genes and alleles in Mendel's experiment.

> explain the relationship between dominant and recessive alleles and phenotype using examples.

For every characteristic, there are two alleles present in pairs in body cells. One of the alleles are dominant, the other is recessive.

What is phenotype?

The dominant and recessive nature of alleles control--->

Dominant alleles are expressed as _____

Provide an example of a dominant allele expressed as a phenotype.

Recessive alleles are expressed as ___

Provide an example of a recessive allele in phenotype.
