Approximately 20% of the world’s adult population are able to digest milk sugar (lactose).They are “lactose tolerant.” This trait is known to be controlled by a single dominant gene. Therefore, we would expect that no lactose tolerant individuals have two biological parents that are lactose INtolerant.

all lactose tolerant individuals to be heterozygous for the gene.

60% of lactose INtolerant individuals would be heterozygous.

all children of lactose tolerant parents will also be lactose tolerant.

No lactose individuals have two biological parents that are lactose intolerant

Explanation:

In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.

answer: "circumcision is a common procedure in which the skin covering the tip of the penis is surgically removed."

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
