Question
Part 4: Should this dog be called Spot? With love from mom and from dad Imagine this microscope drama. A sperm cell from a male dog fuses with an egg cell a female dog. Each dog's gamete carries 39 chromosomes. The zygote that results from the fusion of the gametes contains 78 chromosomes-one set of 39 from each parent. One pair of the zygote's chromosomes are shown above Each chromosome of the homologous pair contains alleles for the same traits But one chromosome may have a dominant allele and the other a recessive allele. Use the drawings and the table to answer the questions. Dominont allele Short (L) Wiry (U Trait Recessive allele Hair length Hair texture Hair curliness Coat pattern Straight h) Solid (a) Spotted (A 1. Will the new puppy have a spotted coat? Explain. 2. Does the female parent have a spotted coat? Explain 3. Does the male parent have a spotted coat? Explain. 4. What will be the texture of the puppy's coat?Explanation / Answer
1 yes, The puppy inherited the dominant allele for spots from its father.
2 She could have a dominant allele on her other chromosome but the information is not given.
3. yes, The male has one dominant allele that he provided to the puppy so we apprehended that the male is spotted.
4.wiry
5.yes The wiry allele is dominant, and both parents possess the dominant allele, which gives them wiry fur
6 Curly
7. a. Unknown.
b. Yes
8. a. Two different alleles
b Hair Length, Hair Curliness, Hair Pattern
9. a.Two identical alleles
b Hair Texture
10. We only possess half of the parents’ genetic data so we cannot acknowledge the phenotype of the parents however we have the whole genotype of the puppy from the parents and so we can hypothesise phenotype from that.
