Question

The diagram in question 6 represents just a few of the chromosomes of meiotic cells in a certain person. Assume the freckles gene is located at the locus marked F, and the hair color gene is located at the locus H, both on the long chromosome. The individual from whom this cell was taken has inherited different alleles for each gene ("freckles" and "black hair" from one parent, and "no freckles" in the gametes resulting from this meiotic event. (It will help if you draw out the rest of meiosis and label the alleles by name.) List other possible combinations of these alleles in this individual's gametes.

Short answer

The allele combinations produced from the meiotic events are 1FH, 1Fh, 1fH, and 1fh.

Step-by-step solution

Description of meiosis

The cell division mechanism that takes place in the germline cell is known as meiosis. There are two types of meiotic division such as meiosis I and meiosis II. The cells produced from meiosis possess half the chromosomal count compared to the parent cell.

Meiosis event of different alleles

The freckles gene is marked on the locus F, and the hair color gene is marked on the locus H. Individuals tend to inherit different alleles such as freckles and black hair from one parent. The allele with no freckles is denoted as f, and no black hair is denoted as h, which is transferred from another parent.

Description of allele combination in the individual's gametes

The possible combinations of the given conditions in the meiotic events are 1FH, 1Fh, 1fH, and 1fh.

1FH shows the expression of the allele such as freckles and black hair. 1Fh shows the allelic expression such as freckles and no black hair.

1fH shows the expression of alleles such as no freckles and black hair. 1fh shows the expression of alleles such as no freckles and no black hair.
