One gene has alleles A and a; another gene has alleles B and b. For each following genotype, what type(s) of gametes will be produced? (Assume independent assortment). a) AA BB b) Aa BB c) Aa bb d) Aa Bb What are the different forms of a...
In the study of genetics, alleles are different forms of a gene. If a gene has two alleles, A and a, and the frequency of allele A is 0.6, what is the frequency of allele a? A. 0.2 B. 0.4 C. 0.6 D. 0.8 相关知识点:
Two new alleles of the rhce gene in black individuals: the rhce allele cemo and the rhce allele cemi: f. noizat-pirenne, i. mouro, p.y. le pennec, et al. br j haematol 113:672–679, 2001doi:10.1016/S0887-7963(02)80079-7Marin E. Reid...
To identify SNPs where the frequencies of the alleles differ significantly between GIH and INS, we calculated Wright’s FST [16] for each of the 1,362,474 autosomal SNPs that are present in both the GIH and INS resources. We used the formula for two populations, given as [Math Processing...
The SNP found in the 3' UTR of the TTR gene has no effect on degrading the variant allele's expression and thus has no impact on the diminished penetrance of the trait in the Swedish population. However, the 3' UTR SNP is unique for patients descending from the Swedish founder, and thi...
In a certain species, the gene for eye color has two alleles. The dominant allele (E) results in brown eyes and the recessive allele (e) results in blue eyes. If a person with genotype Ee mates with a person with genotype ee, what is the probability that their offspring will have brow...

Actually the variation encountered could be regarded mainly as different degrees of modification of the parental types and in only one case has it been necessary to recognise an additional class, gold, for our present purposes. It may also be noted that indication of Brown Leghorn ancestry are ...
The co-existence of males, females and hermaphrodites, a rare mating system known as trioecy, has been considered as an evolutionarily transient state. In nematodes, androdioecy (males/hermaphrodites) as found in Caenorhabditis elegans, is thought to hav
Adiponectin is the product of the ADIPOQ gene, which spans approximately 15.8 kb and three exons. It is sited on chromosome 3q27, which has been linked to a susceptibility locus for metabolic syn- drome, type 2 diabetes and cardiovascular disease (Vionnet et al. 2000; Francke et al. 2001...
