Two brown-eyed parents have produced three blue-eyed sons. what can be concluded about the parents?

Situation in which an individual has actually different alleles comprising his genokind for a details trait


If the man is aa he have the right to donate a or a to his son. The womale deserve to donate A or a. So the possibilities are: Aa, Aa, aa, aaSo 50% of the moment they"ll be Aa, 50% aa. Farsightedness is Aa, so 50%


In humans, farsightedness is inherited by possession of a dominant allele (A). If a guy that is homozygous for normal vision (aa) marries a woguy that is heterozygous for farsightedness (Aa), what propercent of their youngsters would certainly be supposed to be Farsighted? _____%


A metabolic disorder call phenylketonuria (PKU) is as a result of an adnormal recessive gene (p). Only homozygous recessive individuals exhilittle this disorder. What portion of the offspring will certainly be anticipated to have PKU if the paleas are Pp and pp? _____%


Spotted is leading (there are more of them occuring in the same mating pair) Recessive is solid. genokind of parents: Ss X Ss


A man acquired 32 spotted and also 10 solid shade rabbits from a mating of 2 spotted rabbits. Which trait is dominant? Recessive? what is the probable genotype of the rablittle parents? _____x_____


Father: bbMother: BBThe just way to produce a child with blue eyes is bb. This would not be possible then given that just the father has a b allele. Blue eyes son, you can conclude: If the seventh son had blue eyes, the mommy should have actually a b allele also, so the father would certainly be bb and the mom would certainly need to be Bb.

You watching: Two brown-eyed parents have produced three blue-eyed sons. what can be concluded about the parents?


Assume that that allele managing brown eyes (B) is leading over that managing blue eyes (b) in humans. A blue eyed man marries a brvery own eyes womale and they have 6 kids, all brown eyed. What is that many most likely genoform of the father? of the Mother? If the seventh child had blue eyes what can you conclude around the paleas genotype?


For this one given that TT is a normal tail and tt is tail-less, Tt would certainly produce a brief tail because its inin between the 2.Example: Because this is incomplete dominance, tright here is "blending" for circumstances if RR was a red flower, and also rr was a white freduced, Rr would make a pink flower.

Tail size on a bobcat is regulated by incomplete prominence. The alleles are (T) for normal tail length and (t) for tail-less What name could/would you give to the tails of heterozygous (Tt) cats? How would certainly their tail size compare with that of TT or tt bobcats?


If curly-haird individuals are genocommonly CC, strait-haired are cc, and also wavy haired people are heterozygotes (Cc), what portion of various phenotypes would certainly be anticipated from a cross between a CC womale and also a cc man?curly?_____ % wavy_______? strait_______?


Moms bereason males have the right to just obtain the X chromosome from their mothers, the fathers contribution is constantly Y


You are a male and you have been told that hemophilia "runs in your genes" whose ancestors, your mother"s or your father"s need to you investigate? Why?


*

Well the crucial to this trouble is that shade blind is recessive, so bit c. The mother is a carrier.So they could have actually either a daughter that is a carrier (XC)(Xc)A daughter who has colorblindness (Xc)(Xc)A child who is shade blind (Xc)(Y)A son who is not (XC)(Y).

An (XC)(Xc) female marries and also (Xc)(Y) man:What is the probability of developing a color blind son?A color blind daughter?A daughter who is a carrier for the color-blind allele?


Because blook family members have actually comparable gene pools therefore the likelihood of receiving a double-dose of recessive genes is boosted.


The empirical probcapacity is around 12.5%.P(girl) = 0.5Laws of probcapacity dictate event (a) x (b) x (c)= 0.5 x 0.5 x 0.5=0.125=12.5% chance
