Pigment in mouse fur is only produced when the C allele is present- Individuals of the cc genotype are white- If color ispresent, it may be determined by the A, a alleles. AA or Aa results in agouti color, while aa results in black coats.(a) What F1 and F2 genotypic and phenotypic ratios are obtained from a cross between AACC and aacc mice?(b) In three crosses between agouti females whose genotypes were unknown and males of the aacc genotype, thefollowing phenotypic ratios were obtained:(1) 8 agouti(2} 9 agouti(3) 4 agouti10 black 5 blackWhat are the genotypes of these female parents?

(a).From the dihybridized cross between the AACC genotypes with aacc in the first filial generation, 100% of the AaCc genotype representing the genotype of mice with pigment is obtained (f1) because the C allele dominates and Aa results in an agouti color. For the second generation where a cross is made between the genotypes resulting from the F1 AaCc generation. Obtaining the following proportions of phenotypes 9 (agouti with pigment): 3 (white agouti): 3 (black coats with pigment): 1 (black coats and white).

(b). 1.  Genotype of the female: AaCC

2.Genotype of the female:AACC

3.Genotype of the female: aaCC

b. the carbon cycle ensures living things have a source of hydrogen

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
