Answer:
B. after several generations, this trait is likely to be much more common because individuals with the trait will have greater chance of passing it onto their offspring
Answer:
Genotype of the offspring: 4 CC is equal ratio. Phenotype will be 4 yellow cocoons. (CC)
Explanation:
The inheritance of cocoon color in silkworm is a classic illustration of mono-hybrid cross. Mono-hybrid because the color of cocoon is determined by single gene. The yellow color of cocoon is dominant and the homozygous dominant allele is represented as CC. While the white color of cocoon is represented as cc homozygous recessive alleles. As per punnett square method the offspring cocoon color will follow the above mentioned genotypic and phenotypic ratios respectively.
Oxidation would be correct (:
11. What did Charles Darwin think about on his journey home to England?
He noticed the many patterns of diversity in most species and how these differences varied from island to island
12. After Charles Darwin returned to England, what hypothesis he develop to explain his findings?
Separate species arose from a common ancestor.
Answer:
C. tumor suppressor
Explanation:
Tumor suppressor genes encode for proteins which inhibit cell proliferation in some way. One copy of this gene is sufficient to control cell proliferation so both the alleles must be mutated to promote tumor development. Mutation may be a deletion or point mutation.
Tumor suppressor genes are known to code for five classes of proteins:
- Intracellular proteins which inhibit cell proliferation through specific stage of cell cycle
- Receptors for hormones that inhibit cell proliferation
- Apoptosis promoting proteins
- Enzymes involved in DNA repair
- Check point control proteins that arrest cell cycle on detecting any abnormality
