Statistically, it would have been surprising for none of the daughters to be a carrier (and equally surprising for them all to be carriers).
The 50/50 chance of each child of a carrier having the haemophilia gene works quite well when applied to Victoria's descendants.
Victoria herself had nine children, of whom one of her four sons and two of her five daughters had the gene. That is three out of nine, which is on the low side, but Princess Louise's position is unknown because she never had children.
Victoria's daughter Alice of Hesse had two sons, one of whom was a haemophiliac, and five daughters, two of whom were definitely carriers. Ella weas childless and Marie died in infancy, so, again, their position is unknown. There have been recent suggestions that haemophilia has appeared in the descendants of VMH's daughter Alice, but nothing definite on that point. VMH's two sons were healthy and her other daughter was childless.
Alexandra's sister Irene had three sons, two of whom were haemophiliac.
Princess Beatrice had three sons, one of whom was a haemophiliac, and one daughter, who was a carrier (and produced two haemophiliac sons out of four).
Alice of Athlone, daughter of Leopold of Albany, had two sons, one of whom was definitely haemophiliac and the other may have been (he died at six months). Her daughter was not a carrier.
