Genetics question please show as simply as possible how you obtain these answers...
If individual # 1 with genotype AabbCcDdEe is crossed to individual #2 with genotype AaBbCcddee, what is the probability that:. a. individual #1 will produce a gamete with genotype (aBcde) andsimultaneously a gamete with genotype (ABcde)? b. an individual in the Fi population will exhibit a genotype (AabbCcDdEe)? c. an individual in the Fi population will exhibit a recessive phenotype for all traits being considered? Galactosemia is a recessive human genetic disorder that results in the inability to di monosaccharide galactose, which is a metabolic by product of lactose metabolism. results from the inability of the liver to produce the uridyltransferase. As a result, of the inability to catabolize galactose, newborns experience vomiting, jaundice, diarrhea and an inability to gain weight. Death may occur because of E. coli infections at the age of one to two weeks. A normal women, whose father is galactosemic, marries a man whose parents are both galactosemic. The couple has one son with galactosemia gest the enzyme, galactose-1-phosphate a. What is the probability that this couple will have a another female child with galactosemia? Read and think carefully. b. If the couple has 10 children, what is the probability that the first two will be galactosemic, and among the remaining 8, I will have normal galactose metabolism and 7 will be galactosemic? 3. Thinking about Hardy-Weinberg equilibrium. Tell whether the following statements are true or false. You must write the word t-r-u-e or f-a-l-s-e. Please do not give explanations a. (True/False) Hardy-Weinberg relates allelic frequencies to phenotypic frequencies. b. (True/False) Hardy-Weinberg equilibrium requires migration and natural selection to occur within a population. c. (True/False) Hardy-Weinberg equilibrium requires that the allelic frequencies change from parent to offspring. d. (True/False) Hardy-Weinberg equilibrium is dependent on mutation.Explanation / Answer
1). AabbCcDdEd x AaBbCcddee
AaxAa= Aa, Aa, AA, aa
bbx Bb=Bb, Bb, bb,bb
Cc xCc= Cc, Cc, CC, cc
Ddx dd= Dd, Dd, dd, dd
Ee x ee= Ee, Ee, ee, ee
Gametes with genotype aBcde= 3/4x1/2x3/4x1x1=9/32
Gametes with genotype ABcde= 3/4x1/2x3/4x1x1=9/32
2). Probability of the genotype AabbCcDdEe=1/2x1/2x1/2x1/2x1/2=1/32
3). Probability of the recessive genotype= 1/4x1/2x1/4x1/2x1/2=1/128
4). Let a normal women (XX) marries with a men whose both parents are galactosemic
This is a recessive autosomal thats why the man who has both galactosemic parents have 1/2 chances to be galactosemic.
Hence a couple with genotype XX x XgX gives individuals with genotypes
XXg, XX, XXg, XX
the probability of the female child is=1/2x1/4=1/8
5). p=10/2(10-2) (1/4)2 (1/4)10-2
p=8/1(8-1) (1/4)1 (1/4)8-1
p=8/7(8-7) (1/4)7 (1/4)8-7
6). A. Hardy-weinberg relates allelic frequencies with the phentypic frequency but these frequencies are not always equal (p2+2pq+p2)=1
Hence it is True
B. Hardy-weinberg equilibrium requires migration and natural selection to occur within a population is false because Hardy-weinberg equilibrium fail to apply in the occurance of the following circumtances like genetic drift, mutation, natural section etc
D. Hardy-weinberg equilibrium is dependent on mutation is false because Hardy-weinberg equilibrium fail to apply in the occurance of the following circumtances like genetic drift, mutation, natural section etc.
C. Hardy-weinberg equilibrium requires that the allelic frequencies change from parents to offspring is true because the allelic frquency is changed from one generation to next generation
