How is heterozygous inheritance related to recessive inheritance?


Asked by Ricky Salinas on Dec 05, 2021 FAQ



Heterozygousrefers to having two different allelesfor a trait. If one allele is dominant and the other recessive, the recessive trait is masked in the phenotype. 4. In this type of inheritance, one allele for a specific trait is not completely expressed over its paired allele. A pink snapdragon flower exhibits incomplete dominance inheritance..
Also Know,
These genes, whether dominant or recessive, show their effects in the male phenotype. Genes in the differential regions are called hemizygous (“half zygous”) in the males. The X-linked recessive genes show criss-cross pattern of inheritance.
Additionally, X-Linked Recessive Inheritance. X-linked recessive inheritance is designated when phenotypic expression is observed predominantly in males of unaffected, heterozygous mothers. All female offspring of affected males are obligate carriers.
Besides,
This is because an affected female can result only when both mother and father bear the X-linked recessive allele (e.g., XA Xa × Xa Y), whereas an affected male can result when only the mother carries the gene.
Consequently,
None of the sons of an affected male will inherit the X-linked recessive gene, so not only will they be free of the defective phenotype; but they will not pass the gene along to their offspring. In Drosophila, the gene for white eye colour is X linked and recessive to another X-linked, dominant gene for red-eye colour.
