Mitosis is the process in which the chromosome are separated into two identical sets of chromosomes which in the end have their own nucleus. Meiosis is the division in 1/2 and then in 1/2 again causing 4 sets of chromosomes. So, your answer would be m<span><u>itosis produces two genetically identical daughter cells but meiosis produces four genetically different daughter cells.</u></span>

During which phase do the chromosomes make copies of themselves so that there are two of each one?
SashulF [63]

Answer:

The beginning and majority of the time is known as Interphase. Interphase is 80% of the total cycle and is where the cell does most of the work in replicating organelles, chromosomes, and preparing to undergo Mitosis which is the actual splitting process where one cell becomes two. During Interphase there are 3 major steps, G1, S, and the G2 phase.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%

quester [9]

Answer:If a DNA double helix is 100 nucleotide pairs long and contains 25 adenine bases, how many guanine bases does it contain? Well, we have to know the base pairs for DNA first. Adenine only bonds with thymine with two hydrogen bonds, while guanine only bonds with cytosine with three hydrogen bonds. Bonding pairs can also happen vice-versa.
