Q4.4. In a certain species of flowering plant, the allele for red petal color is dominant and the allele for white petal color is recessive. If you mated a homozygous red flower with a homozygous white flower, what would you expect the offspring to look like? All offspring will have red petals. All offspring will have pink petals. All offspring will have white petals. Half of the offspring will have red petals and the other half will have white petals.

5. The horned / hornless traits in sheep are examples of sex-influenced traits. Horned (H) acts as a dominant in rams, while hornless (H’) acts as a dominant in ewes. Thus, the heterozygote exhibits a different phenotype depending upon the sex of the individual. Give the phenotypic results expected in the mating of heterozygous hornless ewes with heterozygous horned rams. Don't use open ai
2 (a) The trait of hen- versus cock-feathering is a sex-limited trait controlled by a single gene. HH and Hh males always exhibit the hen-featuring trait. Only hh males show the cock-feathering trait. Starting with two heterozygous fowls that are hen- feathered, describe how you would obtain a true-breeding line that always produces cock-feathered males. [Ciri berhulu avam hatin
Part 1: Consider three autosomal genes (E, F and G) present in a hypothetical species. The E allele results in male development, the e allele results in female development while the heterozygote develops as a hermaphroditic, sterile individual. The genes at the F and G loci show complete dominance, with the dominant alleles producing long tails (F) and black whiskers (G), while the recessive alleles produce short tails and grey whiskers, respectively. You cross a male with a short tail and black whiskers with a female that has a long tail and black whiskers. All the F1 individuals recovered have long tails, with some having black whiskers and others having grey whiskers. a) What is the sexual phenotype of the F1 offspring? ... b) Another batch of five offspring are expected from the same parents. What is the probability of the first offspring having a long tail and black whiskers?
Achondroplasia is the most common form of dwarfism in miniature horses. Achondroplasia dwarf horses have normal sized bodies and heads, but noticeably smaller upper legs and ears. This form of dwarfism is an autosomal dominant trait. The pedigree shows the offspring of one horse without dwarfism, Individual 1, and one with dwarfism, Individual 2. The horses with achondroplasia are shorter. 1 2

10. In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals? Set up a Punnett square for the dihybrid cross.
Q6.5. Which statement below is TRUE? Crossing over shuffles genes between non-homologous chromosomes. O During meiosis, cells arrange their alleles so that beneficial alleles are passed on together. Without crossing over, offspring would be genetically identical to parents. New combinations of alleles arise from the random events of crossing over, independent assortment, and mutation.
9. Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___

1. A homozygous recessive genotype for the gene that encodes phenylalanine hydroxylase (which breaks down the amino acid phenylalanine) causes lighter skin color, a musty odor, differences in intellectual development, and seizures. 2. In pea plants, alleles of Gene W control flower color, with the dominant allele (W) leading to purple flower color, and the recessive allele (w) leading to white flower color. Usually, a genotype of WW or Ww leads to purple flowers. However, when Gene C is homozygous recessive, WW or Ww plants always have white flowers. 3. In mallard ducks, feather coloring is controlled by Gene F. A dominant allele (F) leads to green head feathers, while a recessive allele (f) leads to brown head feathers. In male mallards, inheritance of one or more F alleles always leads to the green head feather trait. But female mallards always have brown head feathers, regardless of whether they hay are FF, Ff, or ff. a) Multigene (or polygenic) inheritance b) Epistasis c)…
