Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri

Reika [66]

Answer:

0%

Explanation:

This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).

In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:

RRYY- RY, RY, RY, RY

RrYy- RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:

RRYY (4)

RRYy (4)

RrYY (4)

RrYy (4)

According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.

This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%

When peptide bonds form between 2 amino acids, they involve linkage of the ________ group in 1 of the amino acids to the _______

Lesechka [4]

Solution:

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

Thus the required right answer is carboxyl group and other molecule.

When a few drops of hydrogen peroxide are added to a living tissue such as liver or kidney,fizzing or foaming occurs immediately

insens350 [35]

Answer: Peroxides degrade to form oxygen gas, water and foam.

Explanation:

A foam forms when bubbles of a gas are trapped in a liquid or solid. In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver or kidney.
