Phenotype in cattle
Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1). ( 2 votes) Upvote.

WebOur breeding program has put special emphasis on phenotype and breeding for cattle that will be competitive at the national level. Our focus on cattle bred to fit the show ring is also adapting to the industry’s focus on genomics, EPDs, and performance.

WebJul 14, 2024 · An animal can consequently be phenotypically, or visually Black but still carry one copy of either the Red or Wild Type allele, which can then be inherited and expressed by progeny. The Wild Type allele (E+) is considered to be neutral and can produce either a red or black coat colour depending on its interaction with other genes.
