Description
Olivia Katz and five colleagues investigate in 2026 how often chromosomes swap segments during egg and sperm formation in two pig breeding lines. These swaps, called crossovers, shuffle genes and create new combinations for selection. The boar line and sow line had different selection histories, so the team compared crossover counts and positions across both.
Genomic data covered more than 47,000 boars and 78,000 sows typed at over 20,000 markers. Sows passed on about one more crossover per litter parent than boars, with average counts near twenty-one versus twenty in the two lines. Mothers transmitted more crossovers than fathers in both lines. Parents with the highest counts placed swaps nearer chromosome centers, a pattern the authors say breeders should weigh before selecting on crossover number.
