Genetics is the branch of biology that studies how traits are passed from parents to offspring. To better understand genetics, practice problems are often used to help students grasp key concepts. Here, we provide answers to some simple genetics practice problems to help you check your understanding.
In a monohybrid cross, we focus on the inheritance of a single trait. Let’s consider a practice problem where a plant with yellow seeds (Y) is crossed with a plant with green seeds (y). The genotype of the yellow-seeded plant is YY, while the genotype of the green-seeded plant is yy. When these two plants are crossed, all the offspring will have a genotype of Yy, resulting in yellow seeds. Therefore, the answer to this monohybrid cross practice problem is that all the offspring will have yellow seeds.

Dihybrid Cross Practice Problems
In a dihybrid cross, we consider the inheritance of two different traits. Let’s look at a practice problem where we cross a plant with round yellow seeds (RRYY) with a plant with wrinkled green seeds (rryy). In this case, the offspring will all have a genotype of RrYy, resulting in round yellow seeds. Therefore, the answer to this dihybrid cross practice problem is that all the offspring will have round yellow seeds.
By practicing these simple genetics problems and understanding the answers, you can improve your grasp of genetics concepts and be better prepared for more complex genetic problems in the future.
