Genes they assort independently if they follow the 9: 3: 3: 1 rule resulting from a dihybrid cross.
It shows that the genes are not on the same chromosome and they are not included.

Answer and Explanation: To be inherited through mendelian genetics, the traits has to "follow" the 3 principles Mendel described:

1) Principle of Uniformity: All the progeny born from a cross between parents that differ by only one trait will appear identical. Exceptions to penetrance (probability of a gene being expressed), expressity (the different degree a trait express in each individual) and sex-linkage inheritance;

2) Principle of Segregation: The alleles are separated during meiosis, producing equal quantity of gametes (male and female) that contain each allele. So, when one parent carry the dominant trait, the offspring will have the same genotype from the dominant with ratio 3:1;

3) Principle of Independent Assortment: Alleles at one locus separate into gametes independently of alleles at other loci, i.e., each trait is inherited independently from the other. In a dihybrid cross, the proportion of dominant offspring is also approximately 3:1;

In conclusion, traits that follow these "rules", are traits inherited through mendelian genetics.

The answer is; cell surface receptors that are recognized as antigens by the recipient's immune system.

Therefore the organ is attacked as a foreign substance . This is why organ transplants are given by the closest family member to reduce the antigen variability that causes transplant rejection. Tissue typing is done to ensure that the organ or tissue is as similar as possible to the tissues of the recipient.

Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia?

Dominik [7]

Answer:

India was a separate continent until 45 million years ago

Explanation:

India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.

The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.

As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.

What cell organelle can be seen changing position in the moving cytoplasm of elodea?

Tom [10]

Once the cytoplasm of the amoeba is moving, all the cells in the said cytoplasm will move as well. Consequently all the cell organelles can be seen changing positions. The cytoplasmâ€™s ability to move is dependent on the entire composition of cell organelles that make up the said cytoplasm.
