Webhomozygous: [adjective] having the two genes at corresponding loci on homologous chromosomes identical for one or more loci. WebThe law of inheritance was proposed by Gregor Mendel after conducting experiments on pea plants for seven years. Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment. The law of segregation states that every individual possesses two alleles and only one allele is passed on to the offspring.
WebDefine and provide an example of overdominance. Overdominance, also known as heterozygote advantage, is a type of selection where heterozygotes have a higher fitness than both homozygotes. ... is a genetic phenomenon in which heterozygous individuals have higher fitness than either homozygous dominant or homozygous recessive individuals. … WebHomozygous. alleles are both identical for the same characteristic, for example AA or aa. A homozygote is an individual who has identical alleles for a particular gene.
WebAn example of this is the blood group AB which is the result of codominance of the A and B dominant alleles. Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous). For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the ...

WebFor example, an individual who inherits two copies of the gene for brown eyes (BB) from their parents would be homozygous for brown eyes. Homozygosity can have important implications for the expression of genetic traits and the inheritance of genetic disorders, particularly in cases where a recessive allele may cause a disease or disorder.
