• Kangayam (C): Indigenous to Coimbatore, Tiruppur, and Erode districts of Tamil Nadu; renowned for extreme draft power, compact body, and participation in Jallikattu and cattle festivals.
• Other Breeds:
• Kankrej (B): Dual-purpose breed native to Gujarat/Rajasthan (Western India), known for 'Sawai Chaal' gait.

• Sewall Wright $\to$ (II) Path analysis method: Sewall Wright developed path analysis (1921), inbreeding coefficients ($F$), and the shifting balance theory of evolution.
• Hardy $\to$ (IV) Gene frequency Equilibrium: G. H. Hardy (1908) formulated the Hardy-Weinberg law proving that gene and genotype frequencies remain constant under random mating.
• Henderson $\to$ (I) Variance estimation: C. R. Henderson (1953) developed Methods I, II, and III for variance component estimation in unbalanced mixed models and introduced BLUP (Best Linear Unbiased Prediction).
• R.A. Fisher $\to$ (III) ANOVA: Sir Ronald A. Fisher invented the Analysis of Variance (ANOVA), the $F$-distribution, maximum likelihood estimation, and synthesized Mendelian genetics with biometry (1918).

Correct option: (1) (A) - (II), (B) - (IV), (C) - (I), (D) - (III)

• Karyotype of Domestic Cattle (Bos taurus):
• Diploid Chromosome Number ($2n$): 60.
• Autosomes: 58 autosomes (29 pairs), and all autosomes are strictly acrocentric (telocentric).
• Sex Chromosomes:
• X Chromosome: Large submetacentric chromosome (second largest in the genome).
• Y Chromosome: Small submetacentric chromosome in Bos taurus (in contrast, Bos indicus / Zebu cattle has an acrocentric Y chromosome).
• False Statement: Statement (3) claiming "X & Y chromosomes Acrocentric" is false for Bos taurus.

Correct option: (3) X & Y chromosomes Acrocentric
