Explanation / Answer

Thanks for your question. The answers are as follows

1. True

each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

2. False

all the children will have red eyes, as white eye trait is carried on the X chromosome, and the sons recive the Y chromosome from the father.

3.The correct answer is beta carotenoids.

Beta carotenoids are not used as apigment in photosynthesis. While chlorophyll a, chlorophyl b and carotenoids are actively involved in the process.

4. Height is a polygenic trait True

Height is considereda polygenic trait as it is controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.
