Answer:
Explanation:
A gray squirrel can either have the same alllele GG or have two different allele Gg this will determine the percentage of the offspring that will be Grey.
For 2 parent with same allele
GG × GG
!
GG GG GG GG
all are grey 100%
For 2 parents with different allele
Gg × Gg
!
GG Gg Gg gg
75% will be grey
25% other color
The answer is false
When the cells are differentiating in the embryo, they retain the same genetic material. However, certain genes in the differentiating cells are silenced using protein complexes called histones. This makes the genes inaccessible to RNA. Therefore, the process of transcription required in the expression of genes is restricted.
Answer:
a. True
Explanation:
Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.
In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton(which is often called its shell), typically to let the organism grow. ... The new exoskeleton is initially soft but hardens after the moulting of the old exoskeleton.
