Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment
- K is inhibited by the dominant allele D
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white)
Cross: testcross for (Kk Dd) plants
Parental) KkDd x kkdd
Gametes) KD kD Kd kd
kd kd kd kd
Punnet square) KD Kd kD kd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
4/16 Kkdd, blue-flowered plants
4/16 kkDd, white-flowered plants
4/16 kkdd, white-flowered plants
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Blue-flowered plants: 4 Kkdd
White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
Answer: c
Explanation:
the meristem is where the growth occurs.
Since this was a simple abrasion (it would really be the same for anything), this was thanks to the human body's cells multiplying. His damaged skin cells are being replaced with brand new ones, any red blood cells he lost already being replenished.
Answer:- Calvin cycle
Explanation:-
Photosynthesis occurs in two parts:
1. Light dependent reaction which requires sunlight. In this reaction the energy from sunlight gets absorbed by the chlorophyll and is then converted into chemical energy in the form of NADPH and ATP.
2. Light independent reaction which is also known as the calvincycle takes place to provide energy to form carbohydrates using the energized electrons that were obtained from the light dependent reactions. Since, they do not require light for their reaction they can also occur during the night.
