Answer:
The genotype of a black male is XtY
Explanation:
<u>Available data:</u>
- coat color is an X-linked trait with incomplete dominance.
- Yellow coat is caused by the allele XT
- Black coat by the allele Xt.
- Tortoise coat is caused by the heterozygous condition
So,
<u>females genotypes females phenotype </u>
- XTXT → Yellow coat
- XtXt → Black coat
- XTXt → Tortoise coat
<u>males genotype males phenotype</u>
- XTY → Yellow coat
- XtY → Black coat
Males only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.
Females are the only ones that can express the tortoise coat.
