In this image we can see that A is identical to B, and C is identical to D.

Chromatid (Cht) is a DNA molecule (the nucleofilament) associated with histone proteins (PH) and non-histone proteins (PNH)
Each chromosome of a cell may consist of one or two chromatids depending on its state: just after a mitosis, or after the second meiotic division, each chromosome consists of only one chromatid, the rest of the time, after DNA replication, each chromosome consists of two completely identical chromatids, connected by the centromere, thus giving the two rods the shape of an X.

The golden-cheeked warbler and the black-throated green warbler look nearly identical to each other. What type of information co

Lady_Fox [76]

Answer:

The birds do not breed with each other where their territories overlap.

Explanation:

The correct answer would be that the birds do not breed with each other where their territories overlap.

A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.

Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.

Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.

Kobotan [32]

The right option is; A) gametes

Gametes are reproductive cells (male (sperm) or female (eggs)) that contain only half the usual number of chromosomes and unite during sexual reproduction to produce a new cell (zygote). The mutation for sickle cell anemia occurs in the woman’s gamete (eggs) and this type of mutation is known as germline mutation; a mutation that occur in the germ (reproductive) cells and can be passed on to an organism’s offspring.
