In rats, gene b produces black coat color if the genotype is b–, but black pigment is not produced if the genotype is bb. at an independent locus, gene d produces yellow pigment if the genotype is d–, but no pigment is produced when the genotype is dd. production of both pigments results in brown coat color. if neither pigment is produced, coat color is cream. determine the genotypes of parents of litters with the following phenotype distributions. 4 brown, 4 black, 4 yellow, 4 cream 3 brown, 3 yellow, 1 black, 1 cream 9 black, 7 brown

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
