Select the answer that shows the relationship between DNA, gene, allele, locus and proteins.
A proteins make up all of the others (DNA, gene, allele, locus)
B there is a size relationship starting from the smallest to the largest (DNA smallest...proteins largest)
C a gene is a segment of DNA that tells a cell how to make a particular protein; since there are the same genes on chromosomes from the mother and father, each gene can have an alternate expression referred to as an allele. Locus is the location where the gene is found on a chromosome.
D Locus refers to the location that a gene is found on a chromosome. An allele is wrapped around the DNA when it is making a protein.

Phenotype is the physical type of genes/alleles that an organism has for a trait and a Genotype is the physical expression of the genes/alleles of an organism.

A monohyrbrid cross is done with two traits compared to a dihybrid cross which is using only one trait.
A True
B False
C False. Monohybrid is one trait and dihybrid is two traits.

A testcross is used to identify an unknown genotype of an organism by crossing it with a recessive phenotype.
A False.
B True. If the unknown is homozygous dominant, than all of the offspring will have the dominant phenotype.
C True. If the unknown is heterozygous dominant, then the probability for offspring would be 50% showing the dominant trait and 50% showing the recessive trait.
D True, both B and C are correct consequences.

A No.
B Yes.
C Yes. Chromosomes carrying genes line up randomly and separate randomly during meiosis.
44
1
A No.
B Yes.
C Yes. The genes will be far enough apart from each other that crossing over is very likely to occur.
45
1
A No.
B No. The genes are likely to be linked because they are located close to one another and will likely travel together during meiosis.
C Yes. The genes are likely to be linked because they are located close to one another and will likely travel together during meiosis.

The Dragon's activity at classzone doesn't work completely with your chromebook. You are going to do the activity at a different site that will be given to you later. There is nothing for you to enter here.
