Pretty sure he studies pea plants. But he first described the ideas of dominant and recessive genes.

He studied more than just pea plants, but I forgot what else.
Female cats are interesting because, iirc, which X-chromosome inactivation is done in regions rather than individual cells, so you get those grey + white regions, so each region only has one active gene so dominant vs recessive doesn’t matter, but its different in the different regions. Not sure if some genes are autosomal that override it though? I feel like it must be given neither of the parents appear mosaic patterned and yet they have offspring with two different solid-colored offspring.

Sex-linked traits were first described by TH Morgan in fruit fly eyes 40-50 years after Mendel published his pea experiments. It was the first published finding that specifically linked a gene to a chromosome, providing considerable evidence for the chromosome theory of inheritance which was still hotly debated at the time.

Wait, so mummy cat must also carry the recessive allele for the spockles, right?

It could be another allele that is recessive to both grey and spockles. More female offspring would probably tell us more on that.

There are domestic cats with leopard spots? Or are these from a wild species?

Bengal is a cat breed with leopard spots.

Five offspring not fitting in my punnet square! 🤨
