Using the pedigree, which statement is true about Leopold's family?
Olf Leopold had a second male child, that son would have inherited hemophilia.
O Leopold's daughter, Alice, is homozygous recessive for the hemophilia trait.
O Leopold's son can't have a biological female child with hemophilia
The mother of Leopold's children must be a carrier of hemophilia because the daughter is a carrier.

Answer 1

The information about Leopold's family in the pedigree does not provide the necessary evidence to support any of the given statements.

Step-by-step explanation:

Leopold, who is indicated as 'Leopold died in infancy' in the pedigree, was a male child who died in infancy.

Based on the given information, there is no mention of Leopold having a second male child. Therefore, the statement that 'Olf Leopold had a second male child, that son would have inherited hemophilia' is false.

The pedigree does not provide information about Leopold's daughter Alice being homozygous recessive for the hemophilia trait, so the statement that 'Leopold's daughter, Alice, is homozygous recessive for the hemophilia trait' is unsupported.

Similarly, the pedigree does not provide any information about Leopold having a son or the possibility of a biological female child with hemophilia. Therefore, the statement that 'Leopold's son can't have a biological female child with hemophilia' cannot be determined based on the given information.

The pedigree does not provide any direct evidence about the mother of Leopold's children being a carrier of hemophilia. This statement cannot be confirmed or denied based on the given pedigree.
