If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225

There is not enough information to answer this questions. 10 alleles in 1 loci? 10 alleles total? 10 alleles for that gene in the population?
Relationship between a gene and an allele?
Alleles (the alternative forms of a gene found on corresponding loci (specific areas on a chromosome)) are reorganized in a variety of different ways in order to create genetic diversity. 1. Fertilization creates a zygote that is a genetic combination of parent organisms 2. Independent assortment of homologous chromosomes on the metaphase plate during metaphase 1 of meiosis 3. Crossing over during anaphase 1 of meiosis

Are II-1 and II-2 carriers of the trait?
