Step by step
Solved in 2 steps
- In genetics, what does a genotype of Hh signify? Choose 1 answer: Choose 1 answer: (Choice A) A Homozygous; two dominant alleles (Choice B) B Homozygous; two recessive alleles (Choice C) C Heterozygous; one dominant allele and one recessive allele (Choice D) D Homozygous; one dominant allele and one recessive alleleDefine the difference between (a) gene and allele, (b) dominant allele and recessive allele, (c) homozygote and heterozygote, and (d) genotype and phenotype.Color-blindness (c) is a sex-linked recessive trait, while normal color vision (C) is dominant: If two normal-visioned parents have a color-blind son, what are the parent's genotypes? ~What are the chances that their children will be color-blind?
- 1)Explain the differences between the following terms:-Gene, allele, and locus-Genotype versus phenotype- Dominant versus recessiveIf an allele must be present on both the maternal and paternal chromosomes to affect the phenotype, the allele is said to be, (a) dominant. (c) complementary. (b) recessive. (d) heterozygous.Plsssssssss helppppppppp, how can NF1 be spontaneous? Include the following terms: -genotype - phenotype - homozygous - heterozygous - inheritance - alleles - dominant - recessive
- In which of the following cases a person can be heterozygous for a particular trait , and expresses both alleles of that trait ? a) sex-linked inheritance c ) incomplete dominance d) recessive inheritancea. Why males and females do not show equal chances of inheriting a trait? b. Is it possible to determine the genotypes of the parents based on the phenotypes of the offspring?Define the following: (a) polygenic, (b) additive alleles, (c) monozygotic and dizygotic twins, (d) heritability, and (e) QTL.
- Homozygous dominant parent (PP), and a Homozygous recessive or just simply say recessive parent (pp): a. Fill in the Punnett square. Each box represents a genotype possibility for an offspring. b. Place the allele donated by each parent in the corresponding box. Now list the possible genotypes and their corresponding phenotype. c. If an individual's genotype is heterozygous, the dominant trait will be expressed in the phenotype. Give the percent possible for the phenotypes. P P p p Genotype: ______________ Phenotype: ______________ Phenotype % probable: __________ 2. Cross between a Homozygous dominant parent (PP) and a Heterozygous parent (Pp). Fill in as in step one. 3. Cross between a Heterozygous parent (Pp), and another Heterozygous parent (Pp). Fill-in as before. 4. Test cross: A test cross is between a recessive parent (pp), and a Heterozygous parent…In dogs, wire-haired is due to a dominant gene (W), smooth-haired is due to its recessive allele (w). (must show Punnett Square) Two wire-haired dogs are mated. Among the offspring of their first litter is a smooth-haired pup. What is the Genotype of the Parents? () If these, two wire-haired dogs mate again, what are the chances that they will produce another smooth-haired pup? What are the chances that the pup will wire-haired pup? (+) A wire-haired male is mated with a smooth- haired female. The mother of the wire-haired male was smooth-haired. What are the phenotypes and genotypes of the pups they could produce? (t)Information: Rats with one or two brown fur alleles are both phenotypically brown because brown is dominant. Rats with two Albino (white) alleles are phenotypically white. 1. Cross a homozygous Brown male to a White female (she logically is homozygous) Male parent genotype: Possible Sperm: Female parent genotype: Possible Eggs: offspring genotypes & ratios: offspring phenotypes & ratios:
