Answer:
Explanation:
If im correct, the pea plant study was a way to use plants with their different traits to study Dominant and Recessive traits in plants.
He crossed a smoother pea with a more wrinky one and used the offspring as a way to determine dominant and recessive phenotypes.
I may be incorrect but I hope this helps!
The answer is pronuclei. A pronuclei is the state of the
nucleus of either the sperm or the ovum after the sperm has entered the ovum
but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane
of the sperm pronuclei dissolves hence leaving no barrier for the two genetic
materials to combine.
The allele symbols on the outside of the punnett square represent the alleles in the gametes . Because when we done cross we got the gametes only . Example AABB X aabb , then we got the gametes AB and ab . This represent AB and ab are the alles of the gamete only . A allele is the alternative form of gene , if one is dominant other one is recessive.
<span>There are four possible phenotypes with a dihybrid testcross. The 1:1:1:1 ratio means that there is an equal chance of any of the four expected phenotypes in the offspring.</span>
