what's the difference between these- single or multiple genes, and dominant, recessive or sex-linked genes

1 answer:

6 0

A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.

Answer:

Information about flowers

Explanation:

1. A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to affect reproduction, usually providing a mechanism for the union of sperm with eggs.

2. Information about stamen and pollen: The stamen is a male reproductive organ of a flower. It produces the pollen. The stamen has two parts: anther and stalk. After successful pollination, the pollen grain (immature microgametophyte) completes it's development by growing a pollen tube and the two male gametes move through the pollen tube to the ovule.
