Question
When a human embryo is developing, the embryo produces a special type of hemoglobin not found in infant, child, or adult blood.
Which statement best explains how an embryo can produce a different type of hemoglobin from an infant, child, or adult?
Responses
Humans have genes for the different types of hemoglobin, which are expressed at different times.
Humans have genes for the different types of hemoglobin, which are expressed at different times.
The embryo has different genes from the infant, child, or adult.
The embryo has different genes from the infant, child, or adult.
Development and differentiation result in the loss of certain genes.

The statement that best explains how an embryo can produce a different type of hemoglobin from an infant, child, or adult is:
**Humans have genes for the different types of hemoglobin, which are expressed at different times.**
This is because the different types of hemoglobin are produced as a response to the changing oxygen needs and developmental stages of the organism, and the genes that code for these hemoglobin types are regulated to be active or inactive at specific times during development.
