Sexual reproduction results in more genetic variation. Due to small mutations that occur frequently from such, the gene pool is widened. For example, bird feather pigment differences are a result of genetic variation. As a result of this being advantageous, females of that species prefer those males with better color plumage, and thus passes on the gene to future generations.

In squash, yellow seeds are dominant over green seeds. If two heterozygous yellow seed squash were crossed, what are the genotyp
Umnica [9.8K]

Answer:

The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1  and phenotype proportion 3:1

Explanation:

The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.

For the characteristic "seed color" the green color would be G and yellow represented as g.

At the cross of two heterozygous squashs:

- Parents: Gg X Gg

- <u>Punnett's Square</u>:

Alleles    G         g

G           GG       Gg

g           Gg        gg

Offspring:

  • A pumpkin of green seeds GG (25%)
  • Two pumpkins of green heterozygous seeds Gg (50%)
  • One pumpkin of yellow seeds gg (25%)

Genotype proportion 1:2:1

Phenotype proportion 3:1

Inflammatory response is a nonspecific response to?
s344n2d4d5 [400]

The correct answer is: c. Any tissue injury

Inflammatory response is body reaction to disease or injury. Injury triggers an inflammatory response in order to recruit cells (phagocytes come to the damaged area and destroy present microorganisms) and chemicals to the site of the damage to repair it. This process is called inflammation. Inflammation is accompanied by signs and symptoms that include heat, swelling, redness, and pain and it is controlled by the nervous stimulation and chemical substances-cytokines.
