Answer 3

Inheritance of Thin Lips Trait

The inheritance of traits, such as thin lips, is determined by the combination of genes from both parents. In this case, we have a woman with thin lips (recessive trait) and a man with normal lips (dominant trait) who is heterozygous for the thin lips trait.

To determine the possible genotypes and phenotypes of their offspring, we need to consider the genetic makeup of both parents.

Genotypes and Phenotypes

Let's assign the letter "T" to represent the dominant allele for normal lips and the letter "t" to represent the recessive allele for thin lips.

The woman with thin lips is homozygous recessive (tt) for the thin lips trait.

The man with normal lips is heterozygous (Tt) for the thin lips trait.

Now, let's consider the possible combinations of alleles that their offspring can inherit:

1. Offspring genotype: TT - This genotype is not possible because the man does not carry the dominant allele for thin lips.

2. Offspring genotype: Tt - This genotype is possible because the man is heterozygous for the thin lips trait. - The offspring will have normal lips (dominant phenotype) because the dominant allele masks the recessive allele.

3. Offspring genotype: tt - This genotype is possible because the woman is homozygous recessive for the thin lips trait. - The offspring will have thin lips (recessive phenotype) because there is no dominant allele to mask the recessive allele.

Summary

In summary, the possible genotypes and phenotypes of the offspring between a woman with thin lips (tt) and a man with normal lips (Tt) are as follows:

- Genotypes: - Tt (normal lips) - tt (thin lips)

- Phenotypes: - Normal lips (dominant phenotype) - Thin lips (recessive phenotype)

Please note that these predictions are based on the assumption that the thin lips trait is solely determined by a single gene with two alleles. In reality, traits can be influenced by multiple genes and environmental factors, which may result in more complex inheritance patterns.
