The image displays a set of "Doodle Notes" for learning about
Dihybrid Crosses in genetics. Here is a breakdown of the key concepts and rules presented:
1.
What is a Dihybrid Cross?
* It is like a Punnett square, but instead of looking at just one trait (like eye color), it looks at
two traits at the same time (for example, eye color AND fur color).
* Because there are two traits, the grid is larger ($4 \times 4$) and has
16 squares to fill in.
2.
How to Find Parent Gametes (The FOIL Method)
* To solve the cross, you first need to figure out what alleles (gene versions) go into the gametes (sex cells).
* The notes use the
FOIL method from math to help remember the order:
*
First: Take the first letter of each gene pair.
*
Outer: Take the outer letters.
*
Inner: Take the inner letters.
*
Last: Take the last letter of each gene pair.
* *Example from the sheet:* For a parent with genotype
BbYy:
* First: $B$ and $Y \rightarrow BY$
* Outer: $B$ and $y \rightarrow By$
* Inner: $b$ and $Y \rightarrow bY$
* Last: $b$ and $y \rightarrow by$
3.
Dominant vs. Recessive Traits
* The example uses monsters to make it fun:
*
Three eyes (T) is dominant over one eye (t).
*
Blue fur (B) is dominant over orange fur (b).
* This means if a monster has at least one big 'T', it will have three eyes. If it has at least one big 'B', it will have blue fur.
4.
Practice Problems
* The bottom of the sheet shows three different practice scenarios using different creatures (monsters, hedgehogs, and bees) to help students practice setting up the $4 \times 4$ grid and calculating probabilities.
Final Answer:
The image provides educational "Doodle Notes" that teach students how to solve
Dihybrid Crosses (genetic problems involving two traits). It explains that these crosses use a $4 \times 4$ Punnett square with 16 boxes. The main rule taught is using the
FOIL method (First, Outer, Inner, Last) to determine the four possible gamete combinations for each parent before filling in the square. The notes include examples with monsters, hedgehogs, and bees to practice identifying dominant/recessive traits and calculating offspring probabilities.
Parent Tip: Review the logic above to help your child master the concept of dihybrid crosses worksheet.
