White Jersey Giants as far as I know are Recessive White on Extended Black, so she should've been solid black not Transverse Pencilled.Right!? She’s not though! Her momma is a white Jersey giant. I forgot the exact words but we think the momma had a specific gene allowing the barring to be dominant. She looked like a stripey quail as a chick. She’s also got a different comb, waddles and earlobes then my 2 pures. She’s really interesting
Transverse Penciling is made by a combination of genes: Birchen, Dark Brown(Db), & the Pattern Gene which is also responsible for making laced patterns.
