Answer: Meiosis is a phase in sexually reproductive organisms, wherein cell-division takes place. It is of great importance, because it creates genetic diversity in the population.
Explanation:
Answer:
1. heterozygous yellow and star
2. 37
3. 1/8
4. 168
5. 1/4
Explanation:
Given ,
In f1 generation a cross is made between a true breeding black star bellied sneetch mated with a true breeding yellow starless sneetch
yySS x YYss
It is taken as - Y (yellow) is dominant over y (black)
and S (star) is dominant over s (starless)
1. F1 Generation
Genotype of parents yySS X YYss
gametes - yS, yS, Ys, Ys
All 16 offspring will have genotype YySs
phenotype would be heterozygous yellow and star
2. F2 generation cross
YySs X YySs
YS Ys yS ys
YS YYSS YYSs YySS YySy
Ys YYSs YYss YySs Yyss
yS YySS YySs yySS yySs
ys YySs Yyss yySs yyss
Genotype of offspring are –
YYSS – 1
YYSs – 2
YySS – 2
YySs – 4
YYss- 1
Yyss- 2
yySS – 1
yySs- 1
yyss- 1
2. Out of 16, 2 are black star bellied sneetches . Which means only 1/8 are black star bellied sneetches
So out of 300, 37 are black star bellied sneetches
3. Only 2 out of 16 are true breeding. i.e 1/8
4. 9 out of 16 are yellow star bellied sneetches, so out of 300, 168 are yellow star bellied sneetches
5. 4 out of 16 are true breeding yellow. Thus, ¼ are true breeding
Answer:
it would be based on the most common prophase time of year is.
Explanation:
I don't know to be honest.
Answer:
The organism would be genetically almost similar to Tasmanian tiger.
Explanation:
DNA is the genetic material and is responsible for heredity. The DNA present in the nucleus of an egg cell contributes genetic traits of the mother to the progeny. It imparts the progeny some of the genetic traits of the mother.
In the given experiment, DNA from the Tasmanian tiger was introduced into the egg cell of the Tasmanian devil and the transgenic egg cell was allowed to produce a new progeny. Since the implanted transgenic egg cell carried the genetic information from the Tasmanian tiger, the resultant progeny would be almost similar to a Tasmanian tiger.
Answer:
No, proteins don't carry out translation, ribosomes do.
And even if one considered the fact that ribosomes contain proteins (even though it is the ribosomal RNA part that links amino acids together in translation), it still would not be true that the variations in base sequence required more ribosomal proteins.
Explanation:
hope this helps
its the only way i could explain it sorry
