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.

Introduction
Hereditary is determined by genetic factors that are passed on from parents to their offspring. 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. Think of it as reading a book, you never really know what’s…

- please answer Explain Also .arrow_forwardGenetics 181 Rule of Incomplete Dominance When two different pure-breeding strains are crossed, and their offspring show a blending of phenotypes, then neither allele is dominant. This is easily recognized when the phenotype is somewhere between two extremes. Counting the parents, there are three phenotypes (black, white, grey) being expressed in these flowers instead of only two, and that third phenotype is intermediate between the other two. This heterozygous condition is called incomplete dominance. 1. On the chart you did earlier, which of the three hair types (wavy, curly, or straight) represents incomplete dominance-the blended heterozygous condition? 2. You cross a herd of red cattle with white cattle and all of the calves appear to be roan (reddish white). Is this an example of incomplete dominance? How do you know? 3.

A recessive allele blocks the expression of the coat color of fruit flies. Show your answer and solution.arrow_forwardBackground: Each kernel on a cob of corn is a seed for a corn plant. Each kernel can be planted and a whole new corn plant can grow from this kernel. Each cob of corn has hundreds of kernels which were each created by the fertilization of hundreds of eggs from one corn plant and hundreds of pollen from another corn plant. Corn cobs allow for easy genetic analysis because looking at a corn cob is like looking at the hundreds of offspring created from two parents. Corn kernels can come in different colours and textures. It has been determined that purple (P) corn kernels are dominant to yellow (p) corn kernels. Smooth (M) kernels are dominant to shrunken (m) kernels. Purpose: With the use of chi-square analysis, determine if one should accept or reject the hypothesis that both parents that created a cob of corn were heterozygous for colour and heterozygous for texture (PpMm X PpMm).

- Scenario: A 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.
