Question

this passage describes the xeroderma pigmentosum trait in humans:xeroderma pigmentosum is a condition that causes skin to be easily damaged by sunlight. humans with xeroderma pigmentosum avoid exposure to sunlight by wearing protective clothing, using sunscreen, and not going outside during the day.in a group of humans, some individuals have xeroderma pigmentosum and others do not. in this group, the gene for the xeroderma pigmentosum trait has two alleles. the allele e is for not having xeroderma pigmentosum, and the allele e is for having xeroderma pigmentosum.lucy, a human from this group, has xeroderma pigmentosum. lucy has two alleles for having xeroderma pigmentosum.based on this information, click the blue words to correct any errors in the text.lucys phenotype for the xeroderma pigmentosum gene is ee.lucy is heterozygous for the xeroderma pigmentosum gene.lucy does not have xeroderma pigmentosum. this is lucys genotype for the xeroderma pigmentosum trait.

Explanation:

1. For the first sentence: "phenotype" refers to observable traits, while "ee" is the genetic makeup (genotype). The correct term is genotype, since Lucy has two e alleles.
2. For the second sentence: Lucy has two identical e alleles, so she is homozygous, not heterozygous.
3. For the third sentence: Lucy is stated to have xeroderma pigmentosum, so "does not have" is incorrect. Also, having the condition is her observable trait (phenotype), not genotype.

Answer:

1. Lucy's genotype for the xeroderma pigmentosum gene is ee.
2. Lucy is homozygous for the xeroderma pigmentosum gene.
3. Lucy has xeroderma pigmentosum. This is Lucy's phenotype for the xeroderma pigmentosum trait.
