Science Q4

• 
  

  • GENE - are factors that control the appearance of a trait.
• LAWS OF INHERITANCE

  
  

  • STATES THAT DOMINANT TRAIT ALWAYS HIDES OR PREVENTS THE EXPRESSION OF THE RECESSIVE TRAIT.• STATES THAT DOMINANT TRAIT ALWAYS HIDES OR PREVENTS THE EXPRESSION OF THE RECESSIVE TRAIT.
• LAWS OF SEGREGATION

  • STATES THAT DURING SEX CELL FORMATION, THE PAIR OF GENES SEPARATE OR SEGREGATE FROM EACH OTHER AND ARE TRANSMITTED TO THE OFFSPRINGS THROUGH THE EGG AND SPERM CELLS.
• LAW OF INDEPENDENT ASSORTMENT OF GENES • states that the distribution or assortment of one pair of factors is independent of the distribution of the other pair.
• • GENOTYPE - refers to the genetic composition (allelic combination) of an individual.
• • ALLELE - are specific forms/variants of the same gene and are responsible for the variations of the given trait.
• • PHENOTYPE - is the observable trait or the expression of the genotype of an individual for a particular trait.
• HETEROZYGOUS- dissimilar alleles at a particular gene locus. ( Not the same Genes Traits )
• The phenotype is the set of observable physical traits
• The genotype is an organism's genetic information.
• HOMOZYGOUS refers to identical alleles at a particular gene locus. ( Same Genes )
• Homozygous means you've inherited the same alleles of a gene from each of your parents. In contrast, Heterozygous means you've inherited different alleles of a gene from each of your parents.
• BB homozygous dominant
