Recently, genes have been indentified in angiosperms that are important in preventing pollen from germinating or growing into the stigma. the locus where the genes are found has been termed the a. strict reproductive locus b. similarity locus c. selfless locus d. sterility locus

The locus where the genes are found has been termed the sterility locus.The correct option is D.

Explanation:

pollination is defined as the transfer of pollen from the anther to the stigma of the same flower or another flower. There are two types of pollination: self pollination. ( This occurs when the pollen from the anther is deposited on the stigma of the same flower) and cross pollination (transfer of pollen from the anther of one flower to the stigma of another flower).

Recently there are some incompatible genes that prevents pollen from germinating or growing into the stigma of a flower in angiosperms.The locus where the genes are found has been termed the sterility locus. The pollens are either rejected or degraded.The degradation results from the activity of a ribonuclease encoded by the sterility locus. The ribonuclease is secreted from the cells of the style in the extracellular matrix, which lies alongside the growing pollen tube. I hope this helps. Thanks

no they are not always accurate because they can not give you a specific fortune reading they can not tell you exactly what’s gunna happen

the answer for this question would be d. glaciers
