HPV has been recently been implicated as a risk factor for coronary artery disease
Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.
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%.
No wasp have an exoskeleton
I believe the correct response is the third option. Have higher resolution that allows you to view smaller specimens.
