Punnet square worksheet!

help please.

long are W which means that they are stronger than the w trait of short.  

1)the big word means that it will have two W traits, (or W,W), and heterozygous will mean that the seal will have one W and one w, (or W, w).  

your Punnett Square will look like this W     W  which means that 100% of  

these       W W W  W W  

seals        w  W w  W w  

will have long.  

2)Heterozygous and a short will look like this  

           w  W w  w w  

           w   w w  w w  

which means that only 25% will have long and 75% will have short, this is due to how W traits will almost always beat recessive traits.  

3)Now one is, (H) and two is, (h). Two Hybrid means that they are Heterozygous. This will make your Punnett Square look like this                              

       H    h  

 H  H H  H h  

 h   H h  h h  

the possible Genotypes willbe H H, H h, h h.  

Phenotypes, looktraits willbe One,and Two.  

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
