AI Thread Summary
Crossing a homozygous dominant individual (DD) with an unknown genotype will yield offspring that display a dominant phenotype. The possible genotypes of the unknown individual could be DD, Dd, or dd. However, since one parent is homozygous dominant, all offspring will express the dominant trait regardless of the unknown parent's genotype. Thus, the offspring will exhibit a 100% dominant phenotype. This outcome confirms that the presence of a homozygous dominant parent guarantees the dominant trait in the offspring.

1. Homework Statement

Crossing an individual who is homozygous dominant for a trait with an individual whose genotype is unknown will most likely produce which set of offspring?


2. Homework Equations

DD x ? DD x Dd DD x DD DD x dd

3. The Attempt at a Solution

100% dominant phenotype
 
Physics news on Phys.org
Yep, most likely a dominant phenotype.
 
Thanks!

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
