What else can I help you with?
What could cause a mutant fly embryo to develop two tail ends but no head?
This is called bicoid mutant phenotype, and is caused by a maternal effect gene which is a gene that, when mutant in the mother, results in a mutant phenotype of the offspring regardless of the offspring's genotype.
What is the physical representation of a gene called?
a gene is something that you get off your parents eg. your mum has brown hair and blue eyes and your dad has red hair and green eyes and so you have your mothers genes for your brown hair and your fathers green eyes
What is the genotype for males?
The genotype for males is: "XY"
How can an organism with a genotype Gg could have the same phenotype as an organism with the genotype GG?
Dominant alleles are expressed, even if a recessive allele is also present. In the notation used, a capital letter means a dominant allele - therefore the presence of a P (in either PP or Pp) means the organism will display the trait P creates.
Could 2 people with a widows peak have a child with a straight hairline and could 2 people with a straight hairline have a child with a widows peak EXPLAIN?
Yes to the first one, no to the second one. Firstly, widow's peak is caused by a dominant gene while a straight hairline is caused by a recessive gene. Let 'H' be dominant and 'h' be recessive. So for a dominant gene, the trait still will be expressed whether the genotype of the person is homozygous dominant(HH) or heterozygous(Hh). For a recessive gene however, the trait will only be expressed when the genotype of the person is homozygous recessive (hh). So two people with a widow's peak CAN have a child with a stright hairline, provided both of their genotypes are Hh. This is because by crossing their genotypes, they can have a possibility of having child with the genotype HH(widow's peak), Hh(widow's peak), and also hh(straight hairline). The ratio of these three possibilities however, are 1:2:1. So the odds of having a child with a straight hairline in this case is 1:3. If the two people who have widow's peak have the genotype HH or one of them HH and the other Hh, then the possibility of having a child with a straight hairline is 0. This is because by crossing their genotypes together, the genotype of the child will either be HH for the first case, and HH or Hh for the second case. For two people who have a straight hairline, the genotype of both will definitely be homozygous recessive (hh), thus child will definitely have the recessive gene. Therefore, it is not possible for two people with straight hairline to have a child with widow's peak.
What is genotype at the Q gene?
Genotype at the Q gene refers to the specific combination of alleles present at the Q gene locus in an individual's DNA. This genotype determines the individual's genetic makeup and can influence their phenotype or physical characteristics.
What is the difference between an allele and a genotype in genetics?
An allele is a specific version of a gene, while a genotype refers to the combination of alleles that an individual has for a particular gene. In simpler terms, an allele is like a variation of a gene, and a genotype is the specific genetic makeup of an individual for that gene.
What a person's genotype?
Their gene chart
What is the actual gene of an organism is its?
Genotype
Is an allele considered a genotype in genetics?
No, an allele is not considered a genotype in genetics. An allele is a specific form of a gene, while a genotype refers to the combination of alleles an individual has for a particular gene.
What is the genotype of an individual with two different alleles for a specific gene?
The genotype of an individual with two different alleles for a specific gene is called heterozygous.
The actual gene makeup of a organism is its?
genotype
You can be a carrier of a recessive gene as part of your?
You can be a carrier of a recessive gene as part of your genotype.
Is phenotype determine genotype false?
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
What an organsim genotype?
And Organism's genotype is the organism's specific combination of alleles in a any given gene.
What are some examples of a hybrid gene?
hybrid genotype
What is genotype A?
A genotype is an organism's combination of genes that forms a trait.
