Galatians 3:28 has a relevant statement on this question: "....there is neither male nor female.....".
The Watchtower has commented over the years:

8 In the days of the nation of Israel the privileges of women in connection with worship at Jehovah’s temple were very limited. For example, no woman could serve as a Levite priest or take up duties in connection with temple service. No woman was to sit on the throne as ruler in Israel, the only woman to do so being the usurper Athaliah who died because of her presumptuousness. (Num. 3:1-10; 2 Ki. 11:1-20) But, in connection with spiritual Israel, the apostle Paul wrote, addressing his remarks equally to the dedicated women as well as to the dedicated men: “You are all, in fact, sons of God through your faith in Christ Jesus. There is neither Jew nor Greek, there is neither slave nor freeman, there is neither male nor female; for you are all one person in union with Christ Jesus. Moreover, if you belong to Christ, you are really Abraham’s seed, heirs with reference to a promise.”—Gal. 3:26, 28, 29.
9 This meant that women could now share with men the wonderful hope of becoming joint heirs with Christ Jesus in the heavenly kingdom. Some women were now in line to become kings and priests and reign with Christ Jesus along with the rest of the 144,000 Kingdom associates. This, however, would not be as women, but as glorious spirit creatures in the heavens. (Rom. 8:16, 17; Rev. 20:6; 14:1)

Furthermore, God has lovingly drawn a sizable portion of these spiritual heirs with Christ from among women. As to their spiritual standing with God and Christ, there was “neither male nor female” while they were on earth, and in heaven there is no sex principle or distinction. (Gal. 3:28) Nonetheless, those among the Kingdom heirs who have been women know by experience the problems, vicissitudes and thinking of women, and they have maintained integrity under test as women. This is comforting to women who desire to be faithful to God and who seek life under that Kingdom government. How wise our Creator is!

20 It is patently clear from the Scriptures that “there is no partiality with God” with regard to race or sex. (Romans 2:10, 11; Galatians 3:28) And this holds true also in the way Jehovah selects those who are to be associated with his Son in the Kingdom government. (John 6:44) How thankful the great crowd of other sheep can be that faithful women, such as Jesus’ mother Mary, Mary Magdalene, Priscilla, Tryphaena, Tryphosa, and a host of others in the early Christian congregation, now share in the Kingdom rule, enriching that government with their intimate understanding of the feelings and experiences of womenfolk! What loving foresight and wisdom on Jehovah’s part!—Romans 11:33-36.
