This process is called genetic engineering. It is a type of genetic modification wherein engineers can examine the dna<span> of a plant and can add a foreign gene or genes to the genome of an organism. The gene holds information that will give a trait to the organism.</span><span> </span>

Answer:
This is the most amazing thing i have ever seen, keep writing songs.
Explanation:
WOW!
<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
Answer:
2.) Aegilops tauschii contributed two sets of chromosomes, and T. turgidum contributed four sets of chromosomes.
Explanation:
The mating of diploid and tetraploid species is one breeding method which has proven majorly satisfactory with the largest and most prominent mass producers of seedlings for uniform high-quality progeny, has been the mating of the tetraploid of good form with the free and prolific diploid.
The result yields a good progeny. This is due to the fact that the tetraploid parent influences twice as much as the diploid parent do. It's traits, form and color are more pronounced. This also implies that the diploid contributes two chromosomes and the tetraploid contributes four chromosomes. When hexaploid wheat was produced synthetically by He and co-workers, they mated diploid Aegilops tauschii, and the tetraploid species, T. turgidum. This implies that Aegilops tauschii contributed two chromosomes and T. turgidum contributes four chromosomes.
