A heterozygous white rabbit is crossed with a hommozygous black rabbit.  find genotype and phenotypes in ratios.

Within a mouse population, the black fur allele (B) is dominant to the white fur allele (b) and the short whisker allele (S) is dominant to the long-whisker allele (s). A heterozygous black-furred short-whiskered mouse is crossed with a homozygous white-furred long-whiskered mouse. What percentage of the offspring will be black-furred with long whiskers?

Name an allele that is "harmful" in homozygote arrangements yet "beneficial" in heterozygote combinations

If one human parent is heterozygous for blood type A (IAi), and the second parent is heterozygous for blood type B (IBi), what are the expected phenotypic ratios in their children? a. 1/4 with blood type AB, 1/4 with blood type A, 1/4 with blood type B, and 1/4 with blood type O b. 1/4 with blood type A (IAi), 1/2 with blood type AB (IAIB), and 1/4 with blood type B (IBi) c. 1/2 with blood type AB (IAIB), and 1/2 with blood type O (ii) d. 1/2 with blood type A (IAi), and 1/2 with blood type B (IBi) e. 1/2 with blood type A (IAi), and 1/2 with blood type O (ii)

The black fur allele (Y) is dominant to organge (y). The dominant allele is embryonic lethal in homozygotes. two heterozygotes are crossed together. What would be the expected phenotypic and genotypic ratios of it's pups?

What would the genotypes and genotypic ratio be for the F2 generation produced in a phenotype and phenotypic ration of F1 individuals that were produced from a male blue tailed gecko crossed with a female green tailed gecko, being that all 28 of the offspring had green tails, were mated brother and sister?
