Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.66 Non Mendelian Inheritance. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Non-Mendelian Inheritance: Students identify incomplete dominance, codominance, multiple alleles, polygenic traits, and environmental interactions from inheritance patterns and data. Rigor range: standard concept checks through honors/Pre-AP/AP-ready sequence, probability, pedigree, population, and bioethics analysis..

Below are sample questions representative of the exercises included on this worksheet and related 10.66 Non Mendelian Inheritance skill assessments:

Problem 1Difficulty: Mastery

Three crosses for a fictional single gene give these results: A1A2 individuals show phenotype A1, A2A3 individuals show phenotype A2, and A1A3 individuals show phenotype A1. What dominance order is supported?

AA3 > A2 > A1

BA2 > A1 > A3

CAll three alleles are equally codominant

DA1 > A2 > A3

Solution & Explanation:A1 masks A2 and A3, and A2 masks A3, so the dominance order is A1 > A2 > A3.

Problem 2Difficulty: Mastery

A red flower crossed with a white flower produces all red-and-white striped F1 offspring. When F1 plants self-cross, the F2 generation is about 1 red : 2 striped : 1 white. Which pattern is best supported?

AIncomplete dominance

BSimple complete dominance

CCodominance

DEnvironment-only variation

Solution & Explanation:The heterozygotes show both red and white distinctly as stripes, which supports codominance rather than an intermediate blend.

Problem 3Difficulty: Mastery

As the number of genes influencing an additive trait increases, what usually happens to the phenotype distribution in a large population?

AIt collapses to only two phenotypes

BIt has more possible classes and appears more continuous

CIt becomes impossible for environment to matter

DIt always becomes an ABO blood type

Solution & Explanation:More contributing loci create more allele-count combinations, producing a smoother range of phenotypes.
