[QUOTE="inyati13, post: 1046148, member: 17767"] Stated Premises A. GAR Predestined is a carrier (DDC). Aa B. Developmental Duplication (DD) is a defect that exhibits recessive inheritance. C. The dam genotype that was bred to Predestined to produce your Predestined son was a non-carrier. AA The outcome is as follows: 25% AA 25% AA 25% Aa 25% Aa 50% will be homozygous non-carriers (AA); 50% will be heterozygous carriers (Aa) (agrees with robert) But none will exhibit a phenotype of DD or inother words be affected with the malady. If the dam is a carrier (Aa) the outcome is as follows: 25% AA 25% Aa 25% Aa 25% aa 25% will be homozygous non-carriers (AA) 50% will be heterozygous carriers (Aa) 25% will be affected with DD (aa) [/QUOTE]
