Which figure shows homologous chromosomes with heterozygous alleles?

Homologous chromosomes are those chromosomes that are similar in length, centromere location and, gene position. The position of a gene on each homologous chromosomes are same, however, it may contain different alleles.

One of the homologous pairs of a gene is derived from the mother and other from the father. The different form of the same genes is called as an allele.

I dont know what the answer choices are but hope this helps

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
