Leave any statements that are false (that you do not agree with) un- selected.) a two-factor cross of parents that are dominant for both characteristics should result in all progeny being dominant-traited for both characteristics. a one-factor cross of two homozygous parents is expected to have the same phenotypic and genotypiC ratios. a three-factor cross of AaBbDd x aabbdd should result in a 1:1 three-factor phenotypic ratio
- Brown fur vs white fur. Say that the alleles for fur color (brown or white) are written using the letter “B” and “b”. The dominant trait is brown, white fur color represents the recessive trait. If you crossed two heterozygous individuals for fur color, what would be the chances of having an offspring with the white phenotype?Brown fur vs white fur. Say that the alleles for fur color (brown or white) are written using the letter “B” and “b”. The dominant trait is brown, white fur color represents the recessive trait. If you crossed two homozygous recessive individuals for fur color, what would be the chances of having an offspring with the white phenotype?olving Monohybrid Inheritance single gene. crosses. The henotypic traits controlled by a single gene. The problems are to give you practice in problem solving using Mendelian genetics. A dominant gene (W) produces wire-haired texture in dogs; its recessive allele (w) produces smooth hair. A group of heterozygous wire-haired individuals are crossed and their F1 progeny are then test-crossed. Determine the expected genotyplc and phenotypic ratios among the test cross progeny:

- Genetic cross with independent assortment (unlinked traits). Wolves are sometimes observed to have black coats and blue eyes. Assume that these traits are each determined by single genes that are located on different Also assume that normal gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). Suppose that each parent has a normal-colored coat and brown eyes, and that both individuals are heterozygous for both traits.

A couple wants to have a child. However, they both have had Cystic Fibrosis (CF) in their families and so, they want to know if there is a probability of their child inheriting CF. In this couple, if Mom's genotype is AaDD for the Cystic Fibrosis related alleles (as indicated above) and Dad's genotype of Aadd, what would be the phenotypic and genotypic ratios of the children they could have?If any of the children inherit CF, what can you tell about the severity of the disease?
