To exhibit a recessive trait, an individual must have two recessive alleles responsible for the trait. One recessive allele is from a mother and another is from a father. However, if a person has one dominant and one recessive allele, it will not exhibit the recessive trait. This is because recessive allele will be masked by the dominant allele. So, parents must be heterozygous (one dominant and one recessive allele) and must give their recessive alleles to the offspring so that only offspring exhibit the recessive trait.
Except Erythrocytes, <u>because insects do not have the Red Blood Cells</u>.
Erythrocytes- Red blood cells, also known as erythrocytes or RBCs, are biconcave, anucleate cells that contain <u>hemoglobin </u>and carry oxygen and carbon dioxide between the lungs and organs. Erythropoiesis, a process in the red bone marrow, is what creates them.
Hemoglobin- The protein molecule known as hemoglobin is found in red blood cells and is responsible for transporting oxygen from the lungs to the body's <u>tissues </u>and carbon dioxide from the tissues back to the lungs. Four linked protein molecules (globulin chains) make up the hemoglobin molecule.
A collection of cells with similar structures and functions is referred to as a tissue.
