Answer:

Non disjunction at meiosis I results in formation of two daughter cells with one extra chromosome (n+1) and two daughter cells with one less chromosome (n-1).

Explanation:

Failure of homologous chromosomes to separate from each other by the end of metaphase I leads to nondisjunction. The process forms two types of daughter cells: Two daughter cells with n+1 chromosomes (presence of one extra copy of chromosome) and rest two with n-1 chromosomes (absence of one chromosome from the genome).

The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.

Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:  

• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),  

• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and

•  Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)

kkurt [141]

Answer:

The larva gets dark pigment.

Explanation:

If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.

When does fetal erythrocyte production shift from the liver to the bone marrow?
vichka [17]

Answer: After seven months.

Explanation:

The blood carries various substances that must be transported from one part of the body to another. Red blood cells are an important component of the blood because their function is to carry oxygen to the body tissues and exchange it for carbon dioxide, which is carried and removed by the lungs.

Erythropoiesis is the process of red blood cell (erythrocyte) production. It is stimulated by a decrease in O2 in the circulation, detected by the kidneys, which then secretes the hormone erythropoietin. This hormone stimulates the proliferation and differentiation of red blood cell precursors, which triggers an increase in erythropoiesis in hematopoietic tissues and ultimately in the production of red blood cells. <u>In adults, red blood cells are formed in the red bone marrow.</u>

In early developing fetuses, erythropoiesis occurs in the mesodermal cells of the yolk sac. In the third or fourth month, erythropoiesis moves to the liver. After seven months, erythropoiesis occurs in the bone marrow.
