Linked genes practice problems

In humans, the X and Y chromosomes decide biological sex. Males have a “X” and a “Y” chromosome, while females have two “X” chromosomes. One X is given to females by their mother, and the other X is given by their father. Males get an X from their mother and a Y from their father when they are born. Sex-related characteristics alter inheritance patterns in ways that you haven’t seen before.
Females must receive two recessive alleles for a recessive trait on the X chromosome to be expressed. Since there is no matching allele for that phenotype on the Y chromosome, males only need one copy of the allele.

You’ve come to the right location if you’re looking for a worksheet on sex-related characteristics. First, I’ll show you a fantastic, tried-and-true resource that I’ve already prepared to make lesson planning a little easier. Then I’ll give you some suggestions for how you can use this resource to better your teaching and make learning more enjoyable for both you and your students.
This three-page resource includes everything you’ll need to practice Punnett squares with sex-related characteristics, including a response key. It not only has a lot of practice questions, but it also starts with a short reading passage that explains how sex-related characteristics are passed down through the generations. This resource is also available in print and digital formats to make your life easier in any type of learning environment.
I put in the effort so you don’t have to.
It takes a lot of effort to find valuable tools for your lesson. It takes even more effort to make them. I still try to exchange money for time whenever I can. According to thousands of favorable feedback, a few dollars to compensate another classroom teacher for their work in producing valuable tools is a fair swap.

Previous videos discussed the basis for trait inheritance and the effect of alleles on phenotypes. The emphasis of this presentation is on gender and the probability of traits being sex-linked. Sal tells a fantastic story about…
The position of a gene on a particular chromosome is indicated by sex-linked traits. In the videos, students learn about sex-related characteristics and the specifics of color blindness. Then they complete the online interactive to put what they’ve learned into practice…
A hemophiliac’s life expectancy was just 11 years until the 1960s. When there is a sex-linked trait — in this case hemophilia — an insightful video demonstrates how to solve a Punnett square. There is also a discussion of the xy…
Heredity, chromosomal anomalies, sex-related characteristics, and the human genome are all covered in six distinct chromosome activites. The teacher’s preparation of the hands-on activities is fairly straightforward, and they will prove to be both…
When Ms. Strohfeldt created this detailed lesson plan on DNA mutation and sex-linked traits, she left nothing out. As an anticipatory sequence, start with a pretest. Read about the Clark family’s situation and the occurrence of…

Take a look at these slides to get started. Don’t worry if you can’t see the slideshow below; it’s all hidden below. Something in your District’s network settings is blocking your view (and I’m sorry, but I can’t tell you what it is). Sorry for the inconvenience!
Sex chromosomes determine sex in humans, most other animals, and some insects (notably, the well-studied fruit fly). These chromosomes, also known as the X and Y chromosomes, determine sex in the following way:
The X chromosome is far larger than the Y chromosome. As a consequence, the genes on the X chromosome have no corresponding genes on the Y chromosome, as seen in the partial chromosome map on the right.
As a result, genes on the X chromosome are passed down differently than genes on autosomal (non-sex) chromosomes. Let’s take a look at a gene near the bottom of the X chromosome that causes hemophilia to see how.
Hemophilia is a blood condition that runs in families. Hemophiliacs are unable to clot their blood. Though minor cuts are normally unaffected, hemophiliacs have severe internal bleeding issues. How is this disease passed down?
