Chapter 11, Problem 17TYU
Summary Introduction
To explain:
The way in which perpetuation of the genetic information is carried out by the DNA.
Introduction:
The perpetuation of the genetic information from one generation to another iscarriedout with the help of DNA. The DNA is the genetic material that is transferred from parent to offspring and this helps in expressing the traits that are present in the parent, in the child.

1A. Fruit Flies and Genetics Research: Imagine you are working in a genetics lab with the fruit fly Drosophila melanogaster, a model organism for genetics research. You want to determine whether a trait you have discovered in fruit flies is dominant or recessive.• Explain how you would design an experiment to answer this question.• Predict what types of outcomes are possible. Which would indicate that the trait is dominant? Which would indicate that it is recessive?
1.B Model Genetic Organisms: Why are fruit flies considered a model genetic organism? Would humans fit this description?
Genetics Question:
In humans, an allele for black hair in one gene can mask the expression of color on a secondgene. In one family with 10 children, 7 have black hair like their parents, 2 with red hair, and onewith blond hair. The blond child soon came of age and married a man with red hair. All their children have red hair.
a. What specific mode of inheritance is exhibited?
b. Using the letters A and B, assign alleles to the traits
c. Based on the 9:3:3:1 ratio, what are the genotypes of the following:
7 children with black hair ________________ 2 children with red hair ___________________ 1 child with blond hair ____________________
d. Give the COMPLETE genotypes of the following: Parents of the children ____________________ Man with red hair _________________________ All children (of the man) with red hair ________________
The continuity of life is based on heritable information in the form of DNA. In a short essay (100–150 words), explain how chromosome behavior during sexual reproduction in animals ensures perpetuation of parental traits in offspring and, at the same time, genetic variation among offspring.

You suspect there is selection pressure on the color of the flower: bees seem to cluster around the red flowers more often than the blue flowers. In a separate experiment, you discover blue flower color is dominant to red flower color. In a field, you count 600 blue flowers and 200 red flowers. What would you expect the genetic structure of the flowers to be?arrow_forward

Alleles, phenotypes, genotypes, DNA and chromosomes are the basis behind our inheritance; Genetics is the distribution of these genes and the probabilities of their outcomes in the form of traits. Punnet squares are a simple way of determining these outcomes and the resulting traits and offspring. However not all genetics occur as simple as a punnet squares, sometimes alleles are expressed equally rather than one being dominant. This can lead to an expression of codominance, multiple genes and incomplete dominance. Other times alleles are linked based on their location to sex chromosomes or even proximity to each other. This can lead to an expression of sex-linked traits or linked genes. Genetics is a complex field in which multiple factors play a very important role in inheritance, not only Mendelian (basic) genetics.

- Part 1: Define natural selection. In your definition, be sure to explain whether selection acts on traits or genotypes, and what genomic patterns indicate selection has taken place at a locus. Part 2: Generally, would you expect selection to increase or decrease polygenicity of a trait? Explain why.arrow_forward1. In 200 words, explain the role of variation in evolution.arrow_forwardScenario: plant species has flowers that can be red, pink, or white. Flower color is controlled by one gene with two alleles, A (p) and a (q). Red flowers are produced by AA homozygotes, pink flowers are produced by Aa heterozygotes and white flowers are produced by aa homozygotes. A recent survey of 100 of these plants found the following number of different flower colors: 75 plants with red flowers, 20 pink flowers, 5 white flowers. Question: Among 500 plants, how many of the 'AA' genotype are expected under Hardy-Weinberg?arrow_forward
