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.

Background: 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).

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

- 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_forwardScenario: 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.

- Sex-specific imprinting distinguishes male and female genomes and is inherited in a parent-of-origin-specific manner. Such imprints are established in the germline during gametogenesis and remain intact throughout embryonic and postnatal development.

Click on “Search by Species Name” and then click on “Human.” Find 4 disorders that involve imprinting: 2 transmitted from the mother and 2 from the father, and use OMIM to describe the phenotypes (you may include images of phenotypes) and explain their underlying cause(s).

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."
