Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp
10) the cv is wrong; it should be the number of coats of nail polish she applies
11) the iv is wrong; it should be the amount of paperclips on each plane (so basically the weight of each plane)
I don’t really understand the question but i’m assuming that’s there’s a chemical reaction happening when the bicyclist is eating the food to get energy to bike?
Answer:
The correct answer is A DNA is replicated before mitosis begins
Explanation:
DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.
DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.
DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.
