Explanation:

If the DNA codons are altered in an organism, the genetic code will be inaccurate. This will result in genetic mutations and disorders, depending on how drastic the change was. The two types of mutations are point mutations, that just replace one nucleotide. There's also frame shift mutations, where the amount of codons are incorrect.

asambeis [7]

Answer:

The correct answer would be- 1:1:1:1.

Explanation:

According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.

The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.

Thus, the correct answer is : 1:1:1:1.

Is it likely that his body was moved after death? The answer is NO

Why or why not?

This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death

Explanation:

Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.

It helps in judging the time of death for a body, the location and position of the body if it's at the spot.
