Mendelian inheritance specifies that if two heterozygous individuals mate, the chances that a child would be homozygous for the recessive allele would be 25%.

Certain patterns of how qualities are passed from parents to children are referred to as mendelian inheritance. Gregor Mendel, an Austrian monk who conducted countless pea plant tests in the 19th century, developed these broad patterns. A chart known as a Punnett square makes it simple to ascertain the predicted ratios of potential genotypes in the offspring of two parents. The hypothetical situation shown in Figure below.

The gene in question is autosomal, and both parents have heterozygotes for it (Aa). Each parent will generate half the gametes with the A allele and half the gametes with the an allele. The potential genotypes of their offspring are revealed by filling in the Punnett square's cells.

It displays the potential genotype ratios that are most likely to occur, in this case 25% AA, 50% Aa, and 25% aa.

Which organisms evolved from the common ancestor Pakicetus?
pav-90 [236]
Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestor of both these groups was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth. Hope I’ve helped ;)

What molecules produce by the light reactions are used by the Calvin cycles
babymother [125]

Explanation:

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

If bicoid mRNA is injected at the anterior end of an egg from a bicoid mutant mother, what would the phenotype of the resulting
JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.
