Answer:

4 chromosomes

Explanation:

Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).

According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.

Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II
joja [24]

Answer:

A. I, II, III, and V only

Explanation:

In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,

- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.

- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.

- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.

Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

What is runoff and what does it mean
Artemon [7]

Answer:

Runoff is nothing more than water "running off" the land surface.

<h3>Explenation:</h3>

Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
