What is heredity?

The passage of genetic instructions (traits) from parent to offspring.

100

Traits are passed down from  

the parents

G=green eyes. 

If there are all GG in the Punnett Square, the chances of the child having green eyes are

Where are genes located?

In your DNA

Who first studied heredity and the passing of traits from one generation to the next? The Father of Genetics

Gregor Mendel

If alleles are purebred they are also called

homozygous

What is the punnet square used for?

To determine the outcome of genetic crossings.

What are the threadlike structures of DNA that carry genes called?

Chromosomes

What type of organism did Gregor Mendel use to first study heredity?

Pea Plants

If alleles are heterozygous they can also be called 

hybrid

Genes

The physical trait observed in an offspring just by looking at it is known as it's -

Phenotype

For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-

Dominant

Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?

25%

Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygous recessive (e), what is the only possible genotype of the offspring?
