Ose Genetics

different forms of a gene are known as

• Genotypes

• Alleles

a make always accepts his X chromosome:

• from both mom and dad because his XX

• From neither mom or dad because he is XY

• from his mother because the father gives the Y

which statement concerning a pair of alleles for a gene controlling a single characteristic in human is true

• The genes come randomly in pair form either the mother or father

• One gene comes from the mother and one comes from the father

• Both genes come from the mother

Organisms that have two identical allele for a particular trait are said to be

• Hybrid

• Dominant

• Homozygous

if two parent are heterozygous for a genetically inherited dominant trait what is child probability that they will have a child together who has this trait i his or her phenotype.

• 15%

• 60%

• 75%

• 10%

what accounts for the green pea seed in the f2 generation?

• On average, 1 out of 4 offspring of heterozygous parents will be homozygous recessive.

• The f1 generation parent are homozygous yellow

• The yellow is dominant over the green one

Assuming that both parent plants in the diagram above are homozygous why would all of the f1 generation have yellow phenotypes

• Because the f1 genotypes are homozygous.

• Because both parents passed on yellow alleles.

• Because yellow is dominant over green.
