The trait of medium-sized leaves in iris is determined by the genetic condition PP′. Plants with large leaves are PP, whereas pl
dsp73

Answer:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP'   x   PP'

progeny = PP, 2PP', and P'P'

PP = 1/4  x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

<em>Hence the phenotypes would be:</em>

<em>20 large size leaves plants</em>

<em>40 medium sized leaves plants</em>

<em>20 small sized leaves.</em>

What is the main difference between the null and the research hypothesis? What is the importance of assuming the null hypothesis
Ksivusya [100]

Answer:

The null hypothesis is a general statement that states that there

consideration or that there is no association between two groups.

A hypothesis, in general, is an assumption that is yet to be proved

with sufficient pieces of evidence.

Will mark brainliest!!!!
UkoKoshka [18]

That's intimidating, lol!

Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.

Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.

Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.

Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.

This means that choice A is true!
