Drosophila eye color is an X-linked trait. Red eye color is dominant, and white eye color is recessive. Which Punnett square sho
Ira Lisetskai [31]

Answer:

Second Punnett on the first attachment.

Explanation:

In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.

Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).

So taking that all together, you're looking for the genotype combination:

X^{R}Y

So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:

Olin [163]

Answer:

Heterozygous dominant

Explanation:

This means that the genotype has both alleles of the gene hence referred to as heterozygous. The dominant  of the two alleles is the one that is expressed in the phenotype of the individual expressing the genotype. The effects of the recessive allele are masked by the dominant allele.

Discuss why prokaryotic cells probably appeared before eukaryotic cells​
dsp73

Answer:

Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.

Explanation

By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.

Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes
