What is the genotype of a black guinea pig if it is crossed with a whites guinea pig and they have 4 offspring that are black and 2 offspring are white?
Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.
When a black guinea pig is crossed with a white guinea pig and the litter contains a white offspring the genotype of the black haired parent contains?
4 offsprings
A black erminette chicken is crossed with a white erminette chicken what color are the offspring?
The offspring are black feathered because the black feather gene is dominant
When thomas hunt Morgan crossed his red-eye f1 generation flies with each other the f2 generation included both red and white eyed flies why were all the white-eyed flies male?
The white eyed flies that resulted from the crossing of the red-eye flies were all male as the gene involved was on the X chromosome. The X chromosome is the male chromosome.

Explain why morgan did not find white-eyed female d melanogaster in the f2 generation when he crossed white-eyed males with red-eyed females?
In this instance, the gene that expresses the red eyes was dominant and the white eye gene was recessive, so then the f2 generation had no expression of the white eyes..
What is the genotype of a four o clock flower?
If you cross a red 4 O'clock with a white 4 O'clock, the phenotype will be pink This is because red has incomplete dominance over white, so the alleles blend. If yellow is crossed with white, the flowers are always yellow.
The heterozygous of red and white flower color which was co-dominant would be?
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.
Why did one of the characteristics for example dwarfness or white flower color disappear in the F1 generation of Mendal's crosses?
Since the F1 generation of crosses is a cross between two pure traits (for example, TT for tall and tt for short/dwarfness), the offspring of the pure parents all have the genotype of Tt: 100% of offspring will be tall. The dwarfness seems to "disappear" because the capital T is dominant, while the lowercase t (for shortness) is recessive. Dominant dominates a recessive trait, so only tallness appears and dwarfness seems to disappear. Additional Info: However, even though the dwarfness seems to "disappear" it is still in the genotype although it does not appear in the F1 generation. In the F2 generation, there will be a 25% chance of the offspring having the trait dwarfness, because the F1 generation is crossed (Tt x Tt).
Where is the Feathered Hearts in Mayer Arizona located?

What is the genotype of a white eyed female fruit fly?
The white eyed female fruit fly has two recessive traits for eye color. The genotype would be xx for example.
In cattle black coat is dominant to white coat color a farmer has a black male of undetermined genotype how can the farmer determine the genotype of the male?
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.
When Mendel crossed purebred purple flowering plants PP with purebred white flowering plants pp what were the flower colors of the resulting offspring?
Let us assume that both Rr and rr produce red flowers and only rr produces white flowers. Since one parents and the offspring are white, they have rr as genotypes. In order to achieve this result, the other parent would have to haev at least one r in its genotype. Since the otehr parent is red and needs to have one r, it's genotype is Rr. In short, the parents's genotypes are Rr for the red one and rr for the white one.
