Correct Matching
| Trait Type | Example | Key Explanation |
|---|---|---|
| Sex-linked (1-b) | Broodiness in poultry | Gene on Z chromosome (sex chromosome); criss-cross inheritance |
| Sex-influenced (2-c) | Horn condition in Dorset sheep | Autosomal gene; horned allele dominant in males, recessive in females |
| Sex-limited (3-a) | Milk production | Autosomal gene; expressed only in females; responsible for sexual dimorphism |
| Multiple allelism (4-e) | ABO blood group in humans | 3 alleles (Iᴬ, Iᴮ, Iᴼ) at one locus; possible genotypes = N(N+1)/2 = 6 |
| Pleiotropy (5-d) | Double muscling gene in cattle | One gene → muscle hypertrophy + impaired fertility + difficult calving |
ABO Blood Group — Key Facts
| Blood Group | Genotype | Antigen on RBC | Antibody in Plasma |
|---|---|---|---|
| A | IᴬIᴬ or IᴬIᴼ | A | Anti-B |
| B | IᴮIᴮ or IᴮIᴼ | B | Anti-A |
| AB (Universal recipient) | IᴬIᴮ | A & B | Neither |
| O (Universal donor) | IᴼIᴼ | Neither | Anti-A & Anti-B |
