2/3/2024 0 Comments Goat Color GenticsUsing my understanding of goat color genetics, I used Punnet Squares to try and figure out what color kids we will have this year! This is just for fun, and to see if I can become more accurate as I learn more over time.
Each goat has two alleles for color, and they pass one of these to their kids. I can use this fact to create a Punnet Square where each box has 25% of happening. b is medium brown, like Minuet and Chewie. This color needs one copy to be expressed on the goat. B is dark brown; I believe it only needs one copy to be expressed. Sonata is this color, so I don't know what other color gene she carries. G is grey. G needs one copy to be expressed. Strudel is this color. With Chewie and Sonata, two boxes are Bb, which should be expressed as dark brown, like Sonata. Since the other gene that Sonata carries is unknown, we don't know what other color is possible! For Chewie and Strudel, it depends on what gene Strudel carries. Both of Strudel's parents carried Gb, so Strudel is either Gb or GG. If Strudel is GG then all the kids should be grey, but if she is Gb half the kids will be grey and half will be brown. Copper and Minuet is the last case. Minuet has two medium brown genes. Copper has one brown gene as his mother was medium brown and could only give that gene. His other allele is unknown. This means that Minuet and Copper's kids are likely to be 50% brown, and 50% a different color.
