What did you learn today?

What did you learn today?

The ratio is: 2.95: 1 OR 3:1

Where can genes be found? What are alleles?

Genes are found on chromosomes in the nucleus of our cells. Alleles are the two forms of genes one can inherit from their parents.

CH 5 VOCABULARY

Genotype: both inherited alleles together form this; the “genetic” makeup of a trait

Phenotype: an organism’s physical expression of a gene “physical trait”

Vocabulary Example (1 gene=2 alleles)

Genetic Application

Genotype: •  Genetic makeup of

an organism

Represented by (TT, tt, or Tt)

T=dominant allele t=recessive allele

Phenotype: •  Physical

characteristics of an organism

Similar to “trait” •  Actual trait you see face-to-face

•  Physically observing someone with brown eyes

CH 5 VOCABULARYVocabulary Genotype Phenotype

Homozygous: Term used to refer to an organism that has two identical alleles for a particular trait

TT or tt TT= homozygous dominant (tall) tt= homozygous recessive (short)

Heterozygous: Term used to refer to an organism that has two different alleles for the same trait

Tt Tt=tall (dominant trait)

PUNNETT SQUARES

How do we predict traits for future offspring?

Punnett squares: organizes all possible combinations of offspring from specific parents.

We use the alleles to make and fill in the square.

Steps for Punnett SquaresSTEPS:

(1) Fill in (or complete) the Punnett Square.

(2) Record the genotypes you find.

(3) Record the phenotypes you find.

(4) Use probability to explain the chances of a dominant or recessive offspring for both genotype and phenotype.

What are the four steps of mitosis? What is the purpose of mitosis?

What did you learn today?

What did you learn today?

The four steps in mitosis are: prophase, metaphase, anaphase and telophase. The purpose is to divide one cell into two identical cells.

What are the steps of meiosis? What is the purpose of meiosis?

The steps of meiosis are: prophase, metaphase, anaphase, and telophase. The purpose is to have four non-identical cells.

What is a pedigree and why is it important?

What did you learn today?

What did you learn today?

A pedigree is a way to predict the passing on of disorders in a family tree. It is important so families know the probability of passing traits onto their kids.
