Answer:
No, because it is a sign of damage. Although it is better than a burn, it means that DNA has damaged itself. It is the repair mechanism that stimulates more melanin production.
Explanation:
Explanation:
Surprisingly, until recently, not much was known about the genes that control melanin production. 6 were known (MC1R, TYR, OCA2, SLC24A5, MATP and ASIP) and 17 more have been recently identified (DTNBP1, GPR143, HPS3, KITGL, MLPH, MYO5A, MYO7A, SLC45A2, TYRP1, ERCC6, GNAS, HERC2, IRF4, OBSCN, SKC24A5, TPNC2 and MITF), all of them directly or indirectly related to the process of melanin formation and distribution. Since there are so many different genes, if we count all the possible alterations, many different color variants can be produced.
Answer:
II and III
Explanation:
<em>I. All sons of these parents will be a hemophiliac.
</em>
<em>
II. A son who suffers from hemophilia received the hemophilia allele from his mother.
</em>
<em>
III. Half of the daughters of this cross are predicted to be hemophiliacs.</em>
Assuming the haemophilia allele is represented by h, the alternate form being H.
A woman that is a carrier will have the genotype 
.
A man who suffers from haemophilia will have the genotype 
Crossing both of them:
x = 
From the result of the cross, the following can be deduced:
- Half or 50% of the sons from the couple will be haemophiliacs.
- Any son that suffers from haemophilia received the allele from the mother.
- Half or 50% of the daughters from this cross will be hemophiliacs.
Hence, statements II and III are true.
Not sure if this is the format you want it in but
F1:
Genotype: RWHh, RWHh, RWHh, RWHh
Phenotype: basically all of them would have the roan coat and they would be hornless
F2:
Genotype: WWHH, RWHh, RRHh, RWhh
Phenotype: one will have a white coat and hornless, roan coat and hornless, red coat and hornless, roan coat and horned
Hope this somewhat helped
Answer: Peroxides degrade to form oxygen gas, water and foam.
Explanation:
A foam forms when bubbles of a gas are trapped in a liquid or solid. In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver or kidney.
