- Use what you have learned about dominant and recessive alleles to explain why Ravyn
is albino when neither of her parents is abino?
Answer:
Please find the explanation as to why Ravyn is albino when neither of her parents is abino below
Explanation:
According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.
According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.
In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.
