words of genetics and what they mean!

Genotype- the genetic makeup of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration. A genotype consists of two letters that are capital or lower case, an example could be YY or Yy.

Phenotype- the composite of an organism's observable characteristics or traits. these characteristics can be any thing from the color of your hair to the shape of your thumb.

Homozygous- having identical pairs of genes for any given pair of hereditary characteristics. examples for homozygous pairs are XX, yy, tt.

Heterozygous- having dissimilar pairs of genes for any hereditary characteristic. heterozygous pairs can look like these sets, Tt, Yy, Xx.

How can someone predict the traits of offspring?

The most basic way of predicting the traits of a child is by finding the genotypes of the parents and filling out a punnet square.

Why is it important to study the principles of inheritance (how traits are passed on to offspring)?

In humans its not all that important but if you're a animal breeder, its essentially your livelihood to be able to breed the animals in the perfect way.
