SCIENTIFIC INQUIRY

The diagram in question 5 represents a meiotic cell. Assume the freckles gene is at the locus marked F, and the hair-color gene is located at the locus marked H, both on the long chromosome. The person from whom this cell was taken has inherited different alleles for each gene (“freckles” and “black hair” from one parent and “no freckle s” and “blond hair” from the other). Predict allele combinations in the gametes resulting from this meiotic event List other possible combinations of these alleles in this person’s gametes.

SCIENTIFIC INQUIRY The diagram in question 6 represents just a few of the chromosomes of a meiotic cell in a certain person. Assume that the freckles gene is located at the locus marked F, and the hair-color gene is located at the locus marked 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” and “blond hair” from the other). Predict allele combinations 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.   Question is also in the picture.
Think about the same two genes that were mentioned in Question 23—R and T, present in the heterozygous condition as R and r, T and t. Now imagine that the gene for flower color (the alleles R and r) is not on the same chromosome as the gene for plant height (the alleles T and t). Because the two genes are on separate chromosomes, they show independent assortment. What does that mean? When this nucleus undergoes meiosis, it can make gametes with four different genotypes. Why? A very important aspect is that the four different genotypes will be formed in almost exactly equal numbers. Why?
