Conteúdo:	The conservation of genetic resources is crucial for maintaining biological diversity and ensuring the sustainability of animal production. Characterizing regions of homozygosity (ROHs), heterozygosity-rich regions (HRRs), and levels of inbreeding is crucial for the management and conservation of livestock populations. In Brazil, little is known about these genomic parameters in Marota goats. Thus, this study aimed to evaluate these characteristics to support conservation strategies for these breeds. Methods: Genomic analyses were conducted using the Illumina Goat SNP50 BeadChip to investigate ROH, HRR, and to estimate the inbreeding coefficient derived from ROHs (FROH) in Marota and Anglo-Nubian goats. This study evaluated 192 individuals from three distinct herds. ROHs were classified according to their length; genes located within both ROH and HRR regions were identified and functionally annotated to explore their potential biological significance.
