A+ It is probably homozygous for the recessive allele.
No, you have noticed their phenotype.
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
yes they have a brown body with dark spots for camouflage while nesting
OK, this is the general estimate. Not knowing what genes the horses were homozygous and heterozygous for, this is just a rough estimate: 33.34% - Black 33.34% - Bay 33.33% - Chestnut If you know the what the stud and/or the mare is homozygous and heterozgygous for, then you canget a more exact estimate if you go to the link in the relatedlinks.
yes
homozygous dominant is the genotype. hypothetically, if the gene was for the color purple in a flower, the phenotype would be purple, while the genotype would be homozygous dominant AKA Pp.
Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.
it is probably homozygous for the resseive allel
What is the genotype and phenotype of the F1 generation
They would have a genotype pattern of EE.
Well considering that chestnut is recessive the foal most likely would be black, although it could be possible to get a bay foal.
Homozygous recessive; if 'r' stands for color of the seed and 's' for normal starch, then the genotype of this plant used in a test cross will be ( rrss ).
A+ It is probably homozygous for the recessive allele.
it is probably homozygous for the recessive allele
If red color is dominant, (RR) and white is recessive, (rr) then crossing a homozygous red plant with a homozygous white plant will produce 100% red offspring. This is the F1 generation. These F1 offspring will be 100% heterozygous (Rr). Subsequent crosses of these offspring in the second generation (F2) will produce 75% red and 25% white offspring phenotypically (the visual appearance of the color, The genotype ratio will 1 RR: 2 Rr:1rr with percentages of 25% homozygous red 50% heterozygous red and 25% homozygous white.
They refer to the alleles in a genotype. For the basics of genetics, we can say that each allele is either dominant or recessive. Dominant is represented by an uppercase letter, and recessive a lowercase. If the genotype is AA, it is homozygous dominant. If it is aa it is homozygous recessive. If it is Aa, it is heterozygous. Simply, homozygous means that both of the alleles are the same and heterozygous means it has one of each allele.
