Question: please help with these genetic questions i am running out...

Question details

18, Individuals with the genotype GgHhliJj will produce how many different kinds of gametes? Individuals with the genotype of AaBbCC will produce how many different kinds of gametes? 19. For the cross AABBCCDd x AAbbCcDd, what is the probability that an offspring will be AABbCcDd? 20. For the cross CCSS x ccss, what is the probability of having an offspring that is CcSs? For the cross CcSs x CeSs, what is the probability of having an offspring that is ccss? For the cross CeSs x CcSs, what is the probability of having an offspring that is normal for both traits? What type of gametes are produced by an individual with genotype Cc? 21. Polydactyly (extra fingers and toes) is due to a dominant gene. A father is polydactyl, the mother has the normal phenotype, and they have had one normal child. What is the genotype of the father? What is the genotype of the mother? What is the probability that a second child will have the normal number of digits? 22. In cocker spaniels, black coat color (B) is dominant over red (b), and solid color (S) is dominant over spotted (S). If two dihybrids (BbSs) were crossed, what fraction of the black solid offspring would be 2
