Round pea allele R is dominant to wrinkled pea allele r, while yellow pea allele Y is dominant to green pea allele y. Homozygous
allsm [11]

Answer:

RrYy (F1 generation)

Explanation:

This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.

According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.

Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.

In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.

Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.

Time on earth is divided into 6 eras. Three are considered "Precambrian" Which eras are NOT Precambrian?
bulgar [2K]

Explanation:

<u>the  Paleozoic Era </u>

The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.

Just before the Cambrian eruption, in the  Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

Which of the following statements is true? A thin layer of chyme protects the lining of the digestive tract from being broken do
zheka24 [161]

The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.

The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.

When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.
