Answer:

Point mutation

Explanation:

Change in single nucleotide of the DNA is referred to as point mutation. In hemoglobin, point mutation replaces the "adenine base" by "thymine" at the 17th nucleotide of the hemoglobin beta gene. This single nucleotide mutation replace the codon GAG (glutamic acid) to GTG (which encodes amino acid valine) and causes sickle cell anemia.

Name 2 ways a frogs forlimbs are different than the hind limbs
agasfer [191]
Hind limbs will typically be stronger than forelimbs. For some animals this is because they are used for self-defense (a horse or donkey kicking, for example). Forelimbs are not going to be as strong and are often used for feeding oneself, and not intended to be as weight bearing in many mammals.

Is it possible for two albino (all white) to produce a non-albino offspring. Explain
ra1l [238]

Answer:

For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.
