In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
Goryan [66]

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1

Watson and Crick first built a triple-helix model of DNA. In this model, the nitrogenous bases were on the outside of the DNA mo
Sedaia [141]

Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

<h3>What is DNA molecule?</h3>
  • Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
  • Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
  • An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
  • To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.

I need help on this biology question
vichka [17]

Limiting factors for snakes can include frogs, grasshoppers, farmers, pesticides, weather, climate, the environment, and various other abiotic and biotic factors.

Those specified however were also specified within the prompt. These are limiting factors because they can limit or help excel the snake population growth, yet in this prompt it is shown to greatly diminish the growth.

Hope this helps!
