Answer: Option C.
Explanation:
Tumor suppressor genes are genes that help to control cell growth or division. It cause the production of protein which is important in cell growth. It encode protein that slow or inhibit progression in a specific stage of cell cycle leading to DNA repair or cell adhession. If the cells grow uncontrollable, it leads to cancer. When there is mutation of tumor suppressor genes,it result in reduction in its function.
All cells have a plasma membrane and ribosomes. Please correct me if I’m wrong :)
Answer:
1) 36 chromosomes
2) Parent 1 = 24 chromosomes
Non dividing somatic cells = 12 chromosomes
Explanation:
Given data:
F1 hybrid = 9 bivalents + 9 univalents
A. The plant that does not divide F1 has 12 univalents + 12 bivalents. It has 36 chromosomes in total.
Note: 1 bivalent chromosomes consist of 2 chromosomes
B. That parent's non-dividing somatic cell comprises 12 chromosomes, while the number is 24 for parent 1.
Parent 1 = 24 chromosomes
Non dividing somatic cells = 12 chromosomes
Answer:
Positive:
- offspring are all different, therefore more genetic variations that will increase survival.
- diversity
Negative:
- two partners are involved
- undesirable traits could be inherited by the offspring
I hope this helps I’m sorry I couldn’t think of three for each
