What is the phenotype of male?
Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male). Phenotypic sex refers to an individual’s sex as determined by their internal and external genitalia, expression of secondary sex characteristics, and behavior.
What is the phenotype difference between a male and a female?
Generally, phenotypic males had higher body weight (15.25% and 11.36% when the sexes were together or separated, respectively), standard length (3.28% and 2.24%, respectively), and condition factor (2.94 and 2.65, respectively), while phenotypic females had higher liposomatic index (7.11% and 13.69%, respectively) and …
What is the genotypes of the male?
Male Genotype When a sperm carrying the Y chromosome fertilizes an egg, the resulting embryo has a genotype of XY and will be a male. With rare exceptions, all other embryos will be XX or female. Although the Y chromosome codes for a male, the X chromosome is vital for normal human development.
Why are phenotypes different?
An organism’s phenotype results from two basic factors: the expression of an organism’s genetic code, or its genotype, and the influence of environmental factors. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic.
What is the genotype of the male with answer?
Human X and Y chromosomes determine the biological sex of a person, with XX specifying female and XY specifying male. Although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis, the Y chromosome is much shorter and contains many fewer genes.
Do humans have a phenotype?
In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color. And phenotypes aren’t just physical traits. Behavior is also considered a phenotype.
What is the phenotype of an individual XHY normal male carrier male hemophiliac male?
Expression and Transmission
| Phenotype | Genotype |
|---|---|
| Normal male | XHY |
| Normal female | XHXH |
| Affected male | XhY |
| Carrier female | XhXH |
Which genotypes show dominant phenotypes?
A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
Are males heterozygous or homozygous?
Rather than homozygous or heterozygous, males are said to be hemizygous for X-linked genes.
