For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with the genotype RR and a second parent with the genotype rr will have red flowers?

Answers

Answer 1

Answer:

Explanation:

According to the question, the inheritance pattern of flower colour in four o'clock plants follow incomplete dominance i.e. one allele is not completely dominant over the other, and instead they form a heterozygous plant with a third intermediate phenotype (flower colour).

In this case, a four o'clock plant with genotype RR will have red flowers while a plant with genotype rr will have white flowers, Hence, they cross to form an all Rr genotype offsprings with pink flowers (since the red allele is incompletely dominant). Therefore, the percentage chance of having a red flower offspring from this cross is 0%, as it cannot occur.

Explain what has to happen to join two monosaccharide units into a disaccharide.

Answers

Dehydration synthesis is the process by which two monosaccharide are joined to form a disaccharide.

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

A half-life of a radioactive substance is the amount of time needed for one half of _____ to decay into a stable isotope.A) the neutrons in the nuclei

B) its beta particles

C) the nuclei in a sample

Answers

A half-life of a radioactive substance is the amount of time needed for one hald of the nuclie in a sample to decay into a stable isotope.Many protons and neutrons disturb the balance of binding energy from a strong nuclear forces resulting for the nucleus to be unstable. To be in a balance state, the unstable nucleus will give off a proton or neutron through radioactive decay.

nuclie in a sample is the answer
