Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.

Answer:

sweepstake route

Explanation:

From the view of the horses, the ocean barrier would be seen as a  <u>sweepstake route</u>.

<em>By definition, the sweepstake route refers to a rather difficult or dangerous path through which animals can move from one place to another. No animal would take this path ordinarily except by pure chance or when events leave no other option.</em>

In the illustration, no horse would engage in an adventure of swimming across the ocean to North America until the European settlers decided to ferry them across. Hence, to the horses, the ocean barrier represents a sweepstake route.

Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces color
Pie

Answer:

The genes are linked, and the arrangement is coupled (one homolog has both dominant alleles; the other homolog has both recessive alleles).

RY / ry

Explanation:

R_= colored aleurone

rr= colorless aeurone

Y_= green plant

yy= yellow plant

They do a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits (yr/yr) the following F1 is obtained:

  • 88 Colored, green (RY/ry)
  • 92 colorless, yellow (ry/ry)
  • 8 colorless, green (rY/ry)
  • 12 colored, yellow (Ry/ry)

If the genes assorted independently, all of the possible offspring phenotypes would appear in the same frequency. However, they obtained 2 phenotypes much more abundant that the other two. Since recombination is a rare event during crossing over, when two genes are linked the recombinant gametes are produced less frequently than the parentals.

We can propose that the phenotypes Colored, green (RY) and colorless yellow (ry) are the parental gametes, and the unknown plant has the arrangement RY/ry, with both genes linked.

What are two different forms of a single gene called?
sleet_krkn [62]
<span>Alleles are two different forms of single gene that are located in specific position on a specific chromosome. It can be classified into two allele pairs: homozygous and heterozygous. In homozygous, both alleles are the same whether they are both dominant or recessive; while in heterozygous, one allele is dominant and the other is recessive.</span>
