Chapter 14, Problem 17TYU
Summary Introduction
To explain: The passage of genes in the form of alleles from parents to offspring contributes to the perpetuation of parental traits and
Concept introduction:
The transmission of traits into next generations is known as heredity and the heritable information is in the form of DNA. The offspring resemble their parents but are somewhat different; this explains genetic variation.

A species of centipede has a haploid chromosome number of 2. Leg length is controlled by a single gene with two alleles: the long leg allele (L) is dominant to the short leg allele (l). Body coloration is controlled by a single gene with two alleles: the dark allele (D) is dominant to the light allele (d). Leg length and body coloration are encoded by genes on separate chromosomes. Assume the traits obey Mendel’s law of Independent Assortment.

a) A centipede that is homozygous for the recessive allele at both loci mates with a centipede that is homozygous for the dominant allele at both loci. They produce 100 offspring. What fraction of the offspring would you expect to have short legs and light body coloration? Show your calculations and reasoning.
b) Two centipedes that are each heterozygous for both leg length and body coloration mate and produce 100 offspring. What fraction of the offspring would you expect to have long legs and light body coloration? Show your work using a…

- To analyze: According to the given information, wild-type allele of a gene has an A-T base pair at a particular location in its sequence, and a mutant allele of the same gene has a G-C base pair at the same location. Apart from this change, the sequences of the two alleles are same. Based on above information, a question is asked as whether this information tells us anything about the dominance relationship of the allele. If yes, we need to explain why. If no, we need to explain why not.arrow_forwardGive typed full explanationarrow_forwardIn Drosophila, the sepia mutation (se, chromosome 3, position 26) results in dark brown eyes, while cinnabar (cn, chromosome 2, position 57.5) results in bright orange-red eyes.

Bio Question: "In cats, yellow color is due to one allele, and black color is due to another allele. The heterozygous condition results in a color known as tortoise shell, with both alleles expressed. This gene is on the X chromosome. Which is an expected result of a cross between a yellow male and a tortoise-shell female? Mark all answers that apply."

A female mouse named Blanca exhibits albinism. She mated with two male mice, Ash and Whitey, and produced 3 offspring from each mating. • Ash exhibited albinism; all 3 of Blanca and Ash's offspring showed albinism. Whitey exhibited albinism; none of Blanca and Whitey's offspring showed albinism ● Determine the genotype for the offspring of Blanca and Ash. Capital letters denote wildtype alleles, and lower case letters denote mutant alleles. Mice are diploid. aaBB If Blanca and Ash had a fourth mouse in their litter, what is the probability that the fourth mouse will exhibit albinism? 1.0 Determine the most likely genotype for the offspring of Blanca and Whitey.

Choose the definition of uniparental inheritance. One parent transmits all genetic information to all offspring. Two parents transmit combined genetic information to all offspring. Two parents transmit combined genetic information to half of their offspring. One parent transmits all genetic material to only half of the offspring.
