In pea plants, smooth (S) peas are dominant over wrinkled (s) peas in the single gene controlling pea texture. A plant with smoo
OlgaM077 [116]

Answer:

Ss and ss

Explanation:

<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>

<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>

Now, let us look at a cross between the two parents;

  Ss   x   ss

Progeny: Ss, Ss, ss, ss.

Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.

Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.

Hence, the genotypes of the two parents are Ss and ss.

What is the cause of the peripheral edema that often manifests with glomerulonephritis and nephrotic syndrome?.
marta [7]

Answer:

Nephrotic syndrome (also called nephrosis) happens when your kidneys start losing large amounts of protein in your urine. As your kidneys get worse, extra fluids and salt build up in your body. This causes you to have swelling (edema), high blood pressure and higher levels of cholesterol.

Biotechnology is best defined as what?
Lubov Fominskaja [6]
My answer -

<span> Biology is the study of living organisms. Biotechnology involves creating solutions to problems using living organisms. It's more like how mechanical engineering uses machines to solve problems or how computer engineering uses computers to solve problems.

The problems that biotechnology works to solve can range from medical treatments (like stem cells) to advancements in agriculture (disease or drought resistant plants, food with higher nutritional value) to industrial processes (bacteria developed to replace toxic compounds used to make paper, bacteria and algae that produce biofuels).

P.S

Happy to help have an AWESOME!!!! day :)
