?????
How can we predict the color of Baby Fitz’s eyes?
Before we do that lets look at some vocabularySlide5
Vocab for TodayAllele – Versions of a
trait that you get from each parent. Genotype – the combination of alleles for a gene.Phenotype – result of the genotype. The
physical trait. Homozygous – both alleles are the same. Heterozygous – two different alleles.Dominant – overpowers the recessive traits (shown by capital letters)
Recessive –
hidden
by the dominant trait (shown by lowercase letters)Slide6
What does “Homozygous” mean?What does “Heterozygous” mean?What is the dominant genotype?What is the recessive genotype?What is the dominant phenotype?
What is the recessive phenotype?Slide7

?????
Blue eyes are
homozygous recessive
, hazel eyes are
heterozygous
, and brown eyes are
homozygous dominant
. If Mrs. Fitz’s eyes are Homozygous recessive and Mr. Fitz is Heterozygous, what is the percentage that Baby Fitz will have blue eyes? Slide8
Leave enough room on the top and to the leftSlide9
Make Punnett SquareWe know that green eyes are recessive (b) and brown eyes are dominant (B)
Homozygous Dominant = BB = brown eyesHeterozygous = Bb = hazel eyesHomozygous Recessive= bb = blue eyes

Fill in Punnett Square by having each letter fill a box below or to the right. Slide11
Add phenotype probabilities
There is a 50% or 1/2 chance that Baby Fitz will have blue eyes
Hazel eyes = Bb=50%Blue eyes= bb= 50%Slide12

Independent Practice
Answer questions 5 through 8Work must be done silently and independently. No Talking. If you have a question or request raise a silent hand and be patient.
For independent practice, today we will be working silently and independently for 8 minutes.
8
minsSlide14
Group Practice
Questioning:
Ask a question about a specific step.Ask a question related to a specific section of the guided notes.
Discussion
Directly answer each question on your paper by solving each problem step by step.
Directly respond to the questions and comments of peers.
Used discussion stems to promote productive discussion.
Had appropriate section of guided notes open while working on the corresponding section of independent practice.
Maturity & Behavior
Maintain a respectful tone 100% of the time.
Re-evaluate your work when someone had a different answer.
Participate and remain on task 100% of the time.
Show Your Work
Always be able to show evidence for what you state as fact, this is a good time to use your Biology Notebook.
For group work today, we will be using a Discussion Rubric. We will be working at a level two volume. During this time you need to be comparing your answers to make sure you and your table have all the correct answers.
