<span>The plant cell structure that makes the cell become turgin once water enters it is known as A. vacuole. It is a part of a cell that resembles a bubble and where food and water are stored so that the plant can use them and turn them into oxygen. So obviously, when there is water in vacuoles, they become bigger, so the plant becomes turgid, which means that it becomes swollen, swells up.</span>
Answer:
The fraction of the offspring that will show the phenotype produced by the recessive c allele is 1024/4096 = 0.25 A-BbccDdE-Ff = 25%
Explanation:
You can calculate the fraction of the offspring that will show the phenotype produced by the recessive c allele by making the punnet square for each gene and then multipling the phenotypic proportions, like this:
Cross) AAbbCcDDEeff x AaBBCcddEEFF
Cross For each gene by separately:
Gametes) A A A a
F1) 2/4 AA
2/4 Aa
Gametes) b b B b
F1) 4/4 Bb
Gametes) C c C c
F1) 1/4 CC
2/4 Cc
1/4 cc
Gametes) D D d d
F1) 4/4 Dd
Gametes) E e E E
F1) 2/4 Ee
2/4 EE
Gametes) f f F F
F1) 4/4 Ff
So, fraction of the offspring that will show the phenotype produced by the recessive c allele is:
4/4 A- x 4/4 Bb x 1/4 cc x 4/4 Dd x 4/4 E- x 4/4 Ff =
1024/4096 = 0.25 A-BbccDdE-Ff =25%
Answer:
The question lacks options, the options are:
A) 1 out of 16
B) 3 out of 16
C) 6 out of 16
D) 9 out of 16
The answer is 1 out of 16
Explanation:
This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.
When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.
9 represents offsprings that are dominant for both traits
The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.
1 represents offsprings that are homozygous recessive for both traits.
Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.
The number of legs that an arthropod has is a very useful characteristic for classifying them into different classes. Insects always have six legs<span> (three pairs) and arachnids have </span>eight legs<span> (four pairs). Crustaceans have at least </span>eight legs<span> and often more, while myriapods can have up to a hundred legs!</span>
