ASSIGNMENT: FIND THE DEFINITION OF EACH TERM: Punnett Square Homozygous Chromosomes Dihybrid Cross Alleles Recessive Probability Genotypic Ratio Genes Phenotypic Ratio Heterozygous Genotype Monohybrid Cross Phenotype Pedigree Dominant Mendelian Inheritance
Answer (1)
Assignment: Definitions of Genetics TermsPunnett Square – A chart used to predict the possible genetic outcomes of a cross between two organisms.Homozygous – Having two identical alleles for a particular gene (e.g., AA or aa).Chromosomes – Thread-like structures in the cell nucleus made of DNA that carry genetic information.Dihybrid Cross – A genetic cross that involves two traits, each with two alleles.Alleles – Different forms or versions of a gene (e.g., dominant A and recessive a).Recessive – An allele that is masked by a dominant allele and only shows when both alleles are recessive.Probability – The likelihood or chance that a specific outcome will occur.Genotypic Ratio – The ratio of different genetic combinations (genotypes) that appear in offspring.Genes – Units of heredity that are made up of DNA and determine traits.Phenotypic Ratio – The ratio of observable traits (phenotypes) among offspring.Heterozygous – Having two different alleles for a gene (e.g., Aa).Genotype – The genetic makeup of an organism; the combination of alleles.Monohybrid Cross – A genetic cross involving only one trait with two alleles.Phenotype – The physical expression or characteristics of a trait (e.g., tall or short).Pedigree – A family tree that shows how a trait is inherited over generations.Dominant – An allele that masks the effect of a recessive allele in heterozygous condition.Mendelian Inheritance – Patterns of inheritance that follow Gregor Mendel's laws, including dominance, segregation, and independent assortment.
