Bot GPT 3.5 The inheritance of earlobes is determined by a single gene with two possible forms or alleles: attached (A) and unattached (a). The lowercase "a" represents the unattached allele.
In the given sequence "A Aa aa a Aa aa," there are four individuals indicated by the prefix A or a. The chances of offspring having unattached earlobes (receiving the a allele) will depend on the genotypes of the parents.
If the parents are:
1. AA and Aa: The first parent has attached earlobes (genotype AA) and cannot pass on the unattached allele (a). The second parent has one attached allele (A) and one unattached allele (a) and can contribute either allele to the offspring. Therefore, the offspring will have a 50% chance of having unattached earlobes (receiving allele a).
2. aa and Aa (or aa and aa): Both parents have unattached earlobes (genotype aa) and can only pass on the unattached allele (a). In this case, all offspring will have unattached earlobes since they will receive the unattached allele from both parents. Therefore, the percent chance would be 100% in this scenario.
It is important to note that without knowing the respective genotypes of the parents, the specific percent chance cannot be determined accurately.
