Predict the baby’s traits
Here are your parents traits:
Mom: Dad:Dimples=dd No dimples=DDFreckles=FF Freckles=FF
Predict their offspring’s traits by giving a percentage that the baby will have dimples and freckles

Gregor Mendel 1822-1884• Father of modern
genetics• Used pea plants
to demonstrate that certain traits were inherited and followed patterns

Characteristics of the pea plants Mendel studied:• Seed Shape• Seed Color• Tall vs. Short
Plants• Flower Color

Mendel’s Accomplishments:• Used Punnett squares to predict
probability of a trait being expressed• Gene vs. Allele• Heterozygous and Homozygous
alleles• Genotype and Phenotype

Mendel’s Accomplishments:
Alleles can be…Dominant Traits Recessive Traits

Mendel’s Accomplishments:
Incomplete Dominance Codominance

Incomplete Dominance
● Incomplete dominance: heterozygotes have a unique phenotype that is often ‘in between’ the parental types
![Page 9: Monday, February 24, 2014](https://reader035.vdocument.in/reader035/viewer/2022062302/5681656e550346895dd80253/html5/thumbnails/9.jpg)
• Genotypes of the parentsB R = patchwork fishB B = blue fish (Dad)R R = red fish (Mom)
In a certain fish, blue scales and red scales are codominant. What happens if you breed this fish with a fish that only has Blue Scales. What’s the percentage the baby will have patches? (use a Punnett square)
