How many different offspring genotypes are expected in a trihybrid cross between parents heterozygous for all three traits when the traits behave in a dominant and recessive pattern? How many phenotypes?

Explanation:

1. Trihybrid cross contain three genes

as given; parents are hybrid for all the traits;

and one allele is dominant over other allele

So, take three genes named Aa, Bb and Cc; assume i)  allele A is dominant over a, ii) allele B is dominant over b and iii) allele C is dominant over c.

2. Heterozygous parents are: AaBbCc and AaBbCc

there cross produce offspring like; AABBCC, AABBCc, AABbCC, AABbCc, AaBBCC, AaBBCc, AaBbCC, AaBbCc, aaBBCC, aaBBcc, etc

3. So the total phenotype are  8 phenotypes, because dominant allele show their effect in heterozygous condition too.

4.Total genotypes are  27 genotypes;

the national environmental policy act (nepa) is a united states environmental law that promotes the enhancement of the environment and established the president's council on environmental quality (ceq). the law was enacted on january 1, 1970. to date, more than 100 nations around the world have enacted national environmental policies modeled after nepa.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
