Where did the cat pattern come from?

The cat is so funny, where did the cat’s pattern come from?

Determined by differences in embryonic gene expression

Science and Technology Daily, Beijing, September 7 (Reporter Zhang Mengran) A genetic study published on the 7th in the British journal Nature Communications pointed out that the formation of fur patterns (such as stripes) on domestic cats is determined by specific molecules in the developing embryo.

The color of cats is one of the most complicated conditions in mammals.
Even cats of the same breed may “change” their patterns and be mistaken for another breed
.

This time, Gregory Basch of the Alpha Institute of Biotechnology in the United States and his colleagues studied skin samples of domestic cats.
These samples were taken from different developmental stages of non-viable cat embryos.
They also analyzed the findings in tissue sections.

The researchers found that the difference in gene expression in embryos determines the shape of the hair color patterns produced in the later stages of hair growth

Although this study focuses on domestic cats, Basch and co-authors believe that the results may also be applicable to the formation of fur patterns in other mammals such as leopards and tigers
