Meiosis 2 starts with two cells, ends with four.

Meiosis 1 lines up with homologous pairs (Metaphase 1).
Meiosis 2 lines up straight in a line with no pairs (Metaphase 2).

Meiosis 1 one goes from Diploid to Haploid.
Meiosis 2 goes from Diploid to Diploid.

sesenic [268]

Answer:

3000

Explanation:

- Human haploid genome >>> 3 x 10⁹ base pairs >>> 3,000,000,000 base pairs

- Human haploid genome >>> 10⁶ copies >>>  1,000,000 Alu Transposable Elements

- Space between each Alu Transposable Element (TE) >>>

3,000,000,000 base pairs / 1,000,000 Alu elements  = 3,000 base pairs

Alu elements are highly repetitive DNA sequences that account for approximately 20% of the human genome. These sequences (Alu) are considered to be non-autonomous Transposable Elements (TEs) capable of transposing within the genome via an RNA intermediary.

Of inherited from one parent, the skin condition are milk. But when genes are received from both the parents, the disease occurs in its most severe form, also called ichthyosis vulgaris.

Epidermis is the outermost layer of the skin. It is the body's first line of defense because it prevents any microbes entering the body. Besides, it also protects from mechanical injury, stops the loss of moisture and also reduces the effect of UV radiations.
