Answer:
In a given hybridization between two flowers, red “R” is dominant, and white “r” is recessive.in a cross between two white flowered plants, all of the offspring had white flowers ñ. If a plant grower wanted to produce red flowers, what s/he consider during breeding?
rr X rr = rr, rr, rr, and rr
all white flower (recessive homozygous)
such plant grower should cross a true breed or dominant breed of red flower with a white flower
RR X rr= Rr, Rr, Rr, and Rr
All the above flowers are red (dominant heterozygous)
Explanation:
Answer:
1.- Prophase:
Cohesins join sister chromatids of duplicated chromosome.
2.- Prometaphase:
Microtubules attach to kinetochores.
3.- Metaphase:
Kinetochores are motionless in relation to poles of cell.
4.- Anaphase:
Kinetochores move toward poles of cell
5.- Telophase:
Spindle micrutubules disassemble.
A. Avery discovered that DNA was responsible for storing and passing information through generations.
The process of meiosis consists of 8 total stages. Cell division happens twice in meiosis which means that a starting cell can produce a total of four gametes (sperm/egg) on it's own. The four daughter cells produced only have half the amount of chromosomes from the diploid parent cell. Meaning that since it is 'half' the production of meiosis will be a haploid gamete.
