If the offspring is a female, it means she got an X chromosome from her mom, and an X chromosome from her father.
Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
The tissue in the wall of the uterus that is required for labor contractions are SMOOTH MUSCLES. Smooth muscles, also known as involuntary muscles are found in walls of hollow organs such as the stomach, gullet, bronchi, etc. Smooth muscles principally function as stimulator for movement. Examples of smooth muscles in the human body include:
1.Uterus smooth muscles: enhancing pushing during birth labour
2. Bladder smooth muscle: helps push out urine.
3. Smooth muscles also help the flow of blood in the blood vessels and the flow of food through the digestive system.<span />
