In fruit flies, one genotype for red eyes is written XRXR. The R stands for the dominant allele for red eyes. What does the X st
Reil [10]

Answer:

The correct answer is : the female chromosome

Explanation:

  • According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
  • RR is a genotype for Red eyes.
  • A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
  • In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
  • Therefore, XX must represent another trait.
  • By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
  • Given XX genotype represent a female fruitfly chromosome.

Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the chromosomes are haploid or n.
Papessa [141]

Answer:

  • Diploid → Prophase, metaphase, and anaphase
  • Haploid → Telophase

Explanation:

During prophase I,  chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n

During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n

During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n  

In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n

Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.

The two new cells are ready for meiosis II.

In law of superposition which layer is the oldest and which layer is the youngest
Vlada [557]

<u>In law of superposition which layer is the oldest and which layer is the youngest?</u>


Law of superpostion is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy.  In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. The oldest layer would be at the bottem because of how old it is and because of how much other elemnt has been coverd on it. The younges would be on top because it is newer and just got the in the last 100  years.
