Here's the breakdown of the genetics problems: c) Carnation plants show co-dominance for the anthocyanin gene. F^A – allele for anthocyanin pigment (red flowers) F^N – allele for no anthocyanin pigment (white flowers) i) State the genotype of a carnation plant that is heterozygous for this gene. A heterozygous plant has two different alleles. The genotype is F^A F^N. ii) Describe the phenotype of a heterozygous carnation plant for this gene. Since the alleles show co-dominance, both pigments are expressed. The phenotype is Red and white flowers. iii) The breeder crossed a F^A F^N carnation plant with a F^A F^A carnation plant. Predict, using a genetic diagram, the proportion of pure breeding carnation plants in the offspring. Parental genotypes: F^A F^N × F^A F^A Gametes: For F^A F^N: F^A, F^N For F^A F^A: F^A, F^A Punnett square: |c|c|c| & F^A & F^N \\ F^A & F^A F^A & F^A F^N \\ F^A & F^A F^A & F^A F^N \\ Offspring genotypes: F^A F^A, F^A F^N Offspring phenotypes: Red flowers (F^A F^A), Red and white flowers (F^A F^N) Proportion of pure breeding carnation plants: Pure breeding plants are homozygous. In this cross, the homozygous genotype is F^A F^A. There are 2 F^A F^A offspring out of 4 total offspring. The proportion is (2)/(4) or (1)/(2). 3) a) Sex in cats is determined in the same way as in humans. Complete the diagram below to show how sex is determined in cats. Parental genotypes: Male cat (XY) × Female cat (XX) Gametes: Male cat: X, Y Female cat: X, X Punnett square: |c|c|c| & X & Y \\ X & XX & XY \\ X & XX & XY \\ Offspring genotypes: XX, XY Offspring phenotypes: Female, Male That's 2 down. 3 left today — send the next one.
