Understanding Patterns of Inheritance: Purebreds vs. Mutts

Explore the difference in heredity between purebred and mixed-breed offspring through Gregor Mendel's principles. Discover how homologous chromosomes carry genes controlling inherited characteristics, giving offspring a blend of traits from two parents. Dive into true breeding varieties of pea plants, genetic loci, and the law of segregation. Learn how genotype differences can result in identical phenotypes, and understand the physical basis for allele segregation during meiosis.

  1. PATTERNS OF INHERITANCE PUREBREDS OR MUTTS A DIFFERENCE OF HEREDITY

  2. GREGOR MENDEL USE THIS POWER POINT (PICTURE HYPERLINKED TO POWER POINT)

  3. HOMOLOGOUS CHROMOSOMES HOMOLOGOUS CHROMOSOMES OR HOMORLOGUES CARRY GENES CONTROLLING THE SAME INHERITED CHARACTERISTICS

  4. CAN YOU ANSWER…? IT IMPLIES THAT THE OFFSPRING ARE A BLEND OF TWO PARENTS, AS IN A LIQUID MIXTURE 1. WHAT IS A TRUE BREEDING VARIETY OF PEA PLANT? ONE COULD BE HOMOZYGOUS FOR THE DOMINANT ALLELLE, WHILE THE OTHER IS HETEROZYGOUS HOW CAN TWO PEA PLANTS WITH DIFFERENT GENOTYPES FOR A PARTICULAR INHERITANCE BE IDENTICAL IN PHENOTYPE? 3. AN INDIVIDUAL IS HETEROZYGOUS, Gg, FOR A GENETIC LOCUS. ACCORDING TO THE LAW OF SEGREGATION, EACH GAMETE FORMED BY THIS INDIVIDUAL WILL HAVE EITHER THE G ALLELE OR THE g ALLELE. RECALLING WHAT YOU LEARNED ABOUT MEIOSISM, EXPLAIN THE PHYSICAL BASIS FOR THIS SEGREGATION OF ALLELES THE G AND g ALLELES ARE LOCATED ON HOMOLOGOUS CHROMOSOMES, WHICH SEPARATE DURING MEIOSIS AND ARE PACKAGED IN SEPARATE GAMETES
