Answer: A) Black trait is dominant
B) The genotypes of the parents must be Bb
Explanation: Let B represent the allele for black colour and b represent the allele for white colour. If the offspring between 2 black mice show the ratio of 3 black mice to 1 white mouse, it then means that the two parents are heterozygous for black colour, that is each of them have one allele for black colour (B) and one allele for white colour (b). They both have a genotype of Bb.
Bb x Bb = BB, Bb, Bb, and bb.
This means 1BB : 2Bb : 1bb
BB is black, Bb is black while bb is white which gives a ratio of 3 black mice to one white mouse. For Bb to manifest as black, it means that B is dominant to b.
Umm.. well if if you talk about the cell level then the organelles would be cell wall, plastid and a large central vacuole. However if you talk about finding them visually, Leaves, roots and flowers. Pretty simple dude.
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
Explanation:
A recessive trait is a trait that have been expressed when an organism has two recessive alleles or two forms of a gene.
Traits are called the physical/non-physical characteristics of a organisms that can or cannot be observed.
Physical characteristics like hair, eye color can be observed while other characteristics like the shape of blood cells cannot be observed.
It is important to note that if the trait is dominant, one of the parents will have the trait. Dominant traits does not skip a generation. In case the trait is recessive, neither of the parent will have the trait .Recessive trait can skip a generation
So we can say that in the case mentioned in the question
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
If one forgets about food safety it would be a disaster and can cause food poisoning. However if one would just follow the 4 simple steps one's family can be safe from food poisoning.
