2.It is a hybrid because Hh has a dominant trait which is H so the cat is born to be a short haired cat but it is not purely dominant which turns the second cat into a pure recessive
3.All the offspring would be short-haired cats because they would all end up being pure dominant meaning the next generation would be hybrid and not pure anymore
4.The black horse is a hybrid because Bb+bb=Bb and since the allele for the black coat is more dominant then it would be a hybrid
5.It is a hybrid because it is a mix between both a recessive trait and dominant trait and you can only have a pure dominant when it is a cross between two dominants
Answer:
embryo uses food
root grows
seed absorbes water
stem grows
leaves open into seadling
The pairings between nucleic bases, forming "Watson-Crick" base pairs, are, on the one hand, adenine with thymine, and, on the other hand, guanine with cytosine. In addition, two nucleic acid sequences can match only antiparallel, that is to say between segments of opposite directions. Therefore, two nucleic acid sequences are complementary when the nucleic bases of one can pair with the nucleic bases of the other in the opposite direction to form two paired antiparallel segments.
The selective pairing of adenine (A) with thymine (T) and guanine (G) with cytosine (C) is based on the number of hydrogen bonds established between one of the purine bases and the one of the pyrimidine bases:
* Two hydrogen bonds between adenine (purine) and thymine (pyrimidines);
* Three hydrogen bonds between guanine (purine) and cytosine (pyrimidine).
Purity pairs, pyrimidine pairs, adenine-cytosine pair, or guanine-thymine pair are not normally formed. This selectivity is crucial for a large number of biochemical processes involving nucleic acids.
Assuming that you are making the two chromosomes as homologous pairs. You would need to make the two chromosomes relative size because they represent the same genes. One chromosome is from the mom and the other from the dad. If you are making chromosomes for one person they can vary in sizes.
