Answer:
Epistatic interaction of the two genes
Explanation:
In epistasis, the interaction between genes contradics one another, in essence, one gene masks the interference with the expression of another gene. As such any time two different genes contribute and have effects to a single phenotype and their effects are not merely additive, those genes are said to be epistatic.
Answer:
- 120 individuals yySs
- 60 individuals yyss
Explanation:
<u>Available data</u>:
- Two autosomal diallelic genes Y and S
- Y is the dominant allele that codes for yellow
- y is the recessive allele that expresses black
- S is the dominant allele that expresses stars
- s is the recessive allele that codes for starless
- Lethal genotypes: YYss and yySS
1st cross: A true-breeding yellow star bellied sneetch with a true-breeding black starless sneetch
Parentals) YYSS x yyss
F1) 100% YySs
N = 50
2nd Cross:
Parentals) YySs x YySs
Gametes) YS, Ys, yS, ys
YS, Ys, yS, ys
Punnett square) YS Ys yS ys
YS YYSS YYSs YySS YySs
Ys YYSs YYss YySs Yyss
yS YySS YySs yySS yySs
ys YySs Yyss yySs yyss
F1) N = 840
- 14/16 survivers
- 2/16 death YYss and yySS
- 9/16 yellow with stars
- 2/16 yellow starless Yyss
- 2/16 black with stars yySs
- 1/16 black and starless, yyss
14 ------------------ 100% of the progeny --------------840 individuals
2 yySs -----------X = 14.28% ------------------------------X = 120 individuals yySs
1 yyss ------------X = 7.14% ------------------------------X = 59.97 individuals yyss
Haploid means a single set of unpaired chromosomes. Diploid means two complete sets of chromosomes (one from each parent).
Haploid is N and diploid is 2N.
Answer:
ok yes it changes but what is the question
Explanation:
Answer: the reason of why the orange bellied parrots is on the bridge of extinction habitat destruction due to get wood to make house etc. there it could be due to degradation there is almost less than 17 in 2017 of these majestic parrots left and about 310 in cross-breeding in just a few years all of these parrots could be extinct any day these animals could go extinct the orange-bellied parrot is rated as critically endangered on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species. it isn't a matter of will it goes its when it will go extinct
Explanation: well I have facts that point to this answer
