If you were referring to a cross between BB and Bb genotype then the answer would be 50%.

You can figure this out by making a Punnett Square.
       B      b
B   BB    Bb
B   BB    Bb

If you look at the result there is a chance that 2 out of the 4 will have a mixed genotype of Bb. The probability would then be 50%.

Answer:

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.

What makes angiosperm more advance than gymnosperm​
USPshnik [31]

Answer& Explanation:

Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).

1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.

2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
