8A: Monohybrid Crosses
Outcome:
Predict genetic outcomes for a monohybrid cross and a monohybrid test cross
Engage:
Punnett square diagrams are used to predict all the possible gene combinations that could result from the mating of parents with known genotypes for a particular trait. A monohybrid cross represents the inheritance pattern of a single trait.

Complete the following questions.
Use the presentation to answer the following questions:
What is a monohybrid cross?
What phenotypic ratios can we expect from the offspring of:
a. two heterozygous organisms?
b. a heterozygous and a homozygous recessive organism?
c. Give 2 examples of a situation when these expected ratios do not apply
d. For a trait, that is X-linked. A carrier female and a normal male.
An organism is displaying a known dominant trait, but we are unsure whether it is homozygous or heterozygous. How can the organisms genotype be tested?

Complete the Tortoise shell Cat investigation task
using these picture here
This task requires us to identify if there is any specific pattern to the X-inactivation in female cats
Part 2
Read Chapter 8A, complete an annotating the text activity.
Use the following symbols to provide annotations to the text, refer to paragraph (P) and sentence (S)
✓ I can summarise this
X I’m not sure a.k.a. I don’t get it
? I think I get it, but I’m not sure. I still have a few questions
! I can connect this to something else that I have read
→Prediction –I can predict how this may play out
For example. P4 S2, ?, Why does blood typing have 3 different alleles?
