Genetics Genotype & Phenotype Practice worksheet available in printable and digital formats, including a key.

Since the user did not select any of the options (ExplainAnswer, TeachTopic, or GeneratePractice) and simply asked to “solve the problem accurately,” I will interpret this as a request to solve one of the visible practice problems from the worksheet shown in the image — specifically, Problem 13 on the bottom-right sheet:

> 13. female heterozygous for long eyelashes?

This is asking for the *genotype* of a female who is heterozygous for long eyelashes.

Step-by-step reasoning:

First, we need to understand what “heterozygous” means.

- In genetics, “heterozygous” means an organism has two different alleles for a gene — one dominant and one recessive.
- For example, if “L” = dominant allele (long eyelashes) and “l” = recessive allele (short eyelashes), then heterozygous would be “Ll”.

Now, look at the table visible in the top-right part of the image:

It says:
- Trait: Eyelashes
- Dominant Form: Long
- Recessive Form: Short
- Alleles to Use: L or l

So:
- Long eyelashes = dominant → represented by capital letter L
- Short eyelashes = recessive → represented by lowercase letter l

The question asks for the genotype of a female who is heterozygous for long eyelashes.

Note: The sex (“female”) doesn’t affect the genotype here because eyelash length isn’t specified as being sex-linked in this context. So we ignore gender for determining the genotype letters.

Heterozygous = one dominant + one recessive allele → Ll

That’s it!

Final Answer:
Ll
