Answer:
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
Explanation:
Gene controlling seed color are yellow Vs green
Gene controlling seed texture are smooth Vs wrinkled
In F1 generation, A true breeding smooth green plant (SSyy) is crossed to a true breeding wrinkled yellow (ssYY)
Off spring in F1 generation are smooth yellow (SsYy)
This means smooth texture is dominant over wrinkled texture and yellow color is dominant over green
in F2 generation, the cross is carried between SsYy
SY Sy sY sy
SY SSYY SSYy SsYY SsYy
Sy SSYy SSyy SsYy Ssyy
sY SsYY SsYy ssYY ssYy
sy SsYy Ssyy ssYy ssyy
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
Two questions have been asked, and responded to
Answer:
For question 1: The statement is true
For question 2: Yes, the two wild roses are of the same population
Explanation:
Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.
I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.
2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because
- it is still a given area or habitat
- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.
What type of mutation has occurred in figure 12-3?
Answer= substitution
Lysosomes are organelles that float on the cytoplasm and their main function is to secrete waste out of the cell and digest.
Lysosomes are found in eukaryotic cells and yes, they are present in plant cells.
