Question

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?

We say that genes that are close together on the same
chromosome are linked. What does that mean? Imag-
ine that in a diploid nucleus, one chromosome has the
allele R and right next to it on the same chromosome is
the allele T for a different gene. Are these linked? Imag-
ine that r is right next to t on the homologous chro-
mosome. If this cell never undergoes meiosis, does this
matter at all? If it does undergo meiosis, what are the
two genotypes that the gametes are most likely to have?
