Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
It is normal. Your blood type is determined by the genetics of your parents.

Habitat : Native of SE Indochina, and widespread in the East, recently introduced to W Africa and found under cultivation around the coast, particularly from Ivory Coast to Nigeria.The plant requires a somewhat seasonal climate. In thickets and secondary forests at low altitudes.Cultivated, but not as extensively as ubi. Description: Slender, slightly hairy vine, reaching a height of several meters. The tubers are 15-20 cm long. Leaves are simple, suborbicular to reniform, 6-12 cms. apiculate, the base 11- to 15-nervbed, prominently heart-shaped, with rounded lobes. Spikes are slender, axillary, pubescent, up to 50 cm long. Flowers are green, about 4 mm long. A spiny climber to 12 m high twining left-handed, with numerous shallow-rooted tubers, It is a 6-10 months crop with short dormancy period. The tubers are small and are found in clusters of some 5 to 20 slightly below the soil surface. Unselected forms produce spiny roots lying above the tubers as a protection. Selection has eliminated some or all of the spininess in certain cultivars. Yield is high and the tubers are palatable and nutritious. Tubers grown in Ivory Coast have been recorded producing 83% starch and 12% protein. Many races in Asia are slightly sweet. The tubers do not store well. They are quick to sprout if left in the ground and are easily damaged in harvesting. Six months storage is said to be possible of sound roots in a dry well-ventilated store. They are not suitable for transport to distant markets, nor for turning into fufu. There appears to be scope for growing the plant under mechanical cultivation.

Tubers grown in Ivory Coast have been recorded producing 83% starch and 12% protein. Many races in Asia are slightly sweet. The tubers do not store well. They are quick to sprout if left in the ground and are easily damaged in harvesting. Six months storage is said to be possible of sound roots in a dry well-ventilated store. They are not suitable for transport to distant markets, nor for turning into fufu. There appears to be scope for growing the plant under mechanical cultivation. Flowering plants Class : Liliopsida - Monocotyledons Subclass: Liliidae Other Scientific Names : Oneus esculentus Lour. ,Discorea papillaris Blanco ,Discorea tugui Blanco ,Discorea sativa Blanco ,Discorea fasciculata Roxb. ,Discorea tiliaefolia Kunth ,Discorea aculeata Naves Common Names :Aneg (Ibn.),Boga (Ilk.),Dukai (Iv.), Tuñgo (Tag.),Asiatic yam (Engl.) ,aLesser yam (Engl.),Kamiging (Bik.),Luttu (Ibn.),Toñgo (Tag.),Tugi (Tag., Ilk.) Habitat : Native of SE Indochina, and widespread in the East, recently introduced to W Africa and found under cultivation around the coast, particularly from Ivory Coast to Nigeria.The plant requires a somewhat seasonal climate. In thickets and secondary forests at low altitudes.Cultivated, but not as extensively as ubi. Description: Slender, slightly hairy vine, reaching a height of several meters. The tubers are 15-20 cm long. Leaves are simple, suborbicular to reniform, 6-12 cms. apiculate, the base 11- to 15-nervbed, prominently heart-shaped, with rounded lobes. Spikes are slender, axillary, pubescent, up to 50 cm long. Flowers are green, about 4 mm long. A spiny climber to 12 m high twining left-handed, with numerous shallow-rooted tubers, It is a 6-10 months crop with short dormancy period. The tubers are small and are found in clusters of some 5 to 20 slightly below the soil surface. Unselected forms produce spiny roots lying above the tubers as a protection. Selection has eliminated some or all of the spininess in certain cultivars. Yield is high and the tubers are palatable and nutritious.
