Eye pigment in a particular strain of fly is determined by two genes. An autosomal gene that controls the color of the pigments
Semenov [28]

RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.

Option D

<h3><u>Explanation:</u></h3>

The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.

As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.

As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.

So the most possible cross that is given here is RrXtXt×RrXTY.

If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell?
frozen [14]
Not necessarily.
Rather, the particles will continue moving, but the net amount stays the same because they’re moving at a constant rate. The amount of movement does tend to slow down, but it still continues

Meiosis does PMAT twice! That means there is a prophase I and a prophase 2. There is a metaphase1 and metaphase 2. Etc... How wo
Gennadij [26K]
<h3><u>Answer;</u></h3>

In metaphase I, the chromosome tetrads align on metaphase plate while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.

<h3><u>Explanation;</u></h3>
  • Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes .
  • Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
  • During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
