For those of you who don’t know‚ albinism is a hereditary condition in which affected organisms have either complete or partial absence of pigment in skin‚ hair‚ eyes‚ or all of the above. This condition is quite unique and interesting‚ and we are here to fill you in on five intriguing facts you didn’t know about albino animals! Number Five: Appearance The appearance of albino animals is similar to that of normal

Purpose To provide practice in using appropriate methods to answer questions and solve problems about monohybrid inheritance. Questions Q1 Some forms of albinism‚ a genetic disorder‚ may be due to a single gene mutation. The allele for albinism is recessive to the allele for no albinism. A woman is heterozygous for albinism. Her male partner is homozygous for the ‘normal’ allele. a Does the woman suffer from the condition? no b What percentage of their children are likely to be carriers

Problem Set – Monohybrid and Dihybrid Cross 1. Classical albinism results from a recessive allele. What is the expected offspring from a normally pigmented male with an albino father and an albino wife? 2. A pea plant with red flowers is test crossed and one half of the resulting progeny have red flowers‚ while the other half has white flowers. What is the genotype of the test crossed parent? 3. If we cross two pea plants each heterozygous for yellow seed color genes‚ what would be the

Captain Ahab’s great white whale brings him destruction in the famous “Moby Dick”‚ but actual whales glide graceful and effortless through the ocean almost all of time. After the white whale in “Moby Dick”‚ there is perhaps no whale more well known among enthusiasts and scientists alike than Migaloo the white humpback whale. Migaloo the white humpback whale has been spotted this week off the coast of New Zealand as he makes his annual migration to warmer waters. Migaloo the white humpback whale is

Mutation is a change in the nucleotide arrangement of a short locale of a genome. Numerous mutations are point mutations that supplant one nucleotide with another; others include insertion or deletion of one or a couple of nucleotides. Mutations result either from errors in DNA or from the harming impacts of mutagens‚ for example‚ chemicals and radiation‚ which respond with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the
