How does reproductive isolation result in speciation

Biology

Speciation is the adaptive divergence and gradual that leads to two different species.

Reproductive isolation results in speciation when the processes of evolutionary mechanisms, physiological and behaviours are collected.

Mechanism of reproductive isolation helps in preventing members of different species from producing offsprings. A zoologist is a classified way of reproductive isolation whereby it(zoologist) is classified to the mechanism of reproductive isolation into two categories

(i)                  Pre-zygotic. This one acts before fertilization or before mating when it comes to animals.

(ii)                Post-zygotic. It acts after fertilization.

The mechanisms appear I species which are genetically controlled and whose geographic distribution overlaps or are separated.

Helper T cells are very important cells in the adaptive immunity. They are required for almost all adaptive immune responses and They also help activate cytotoxic T cells and macrophages to attack infected cells.

Noe is studying Wave A and Wave B. Wave A is rated at 100 dB, and Wave B is rated at 90 dB. Which statement can be made about th
Vera_Pavlovna [14]

Answer: B.  Wave A is louder than Wave B.

Explanation: The loudness of sound is measured in unit called decibels (dB).

A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.

Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.

Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.

Conduct a dihybrid cross of pea plants with the following combination of traits: Parent 1—Tall plant with white flowers (pure br
Angelina_Jolie [31]

Answer:

i) Genotype of Parent 1= TTpp

Genotype of  Parent 2= ttPP

ii) The genotypes of their gametes

Parent 1= Tp

Parent 2= tP

iii) F1 generation = All TtPp (tall and purple flower)

iv) F2 phenotype ratio= 9 tall, purple: 3 tall, white: 3 dwarf, purple : 1 dwarf, white.

F2 Genotype ratio= 1:2:1:2:4:2:1:2:1

Explanation:

Let's assume that allele "T" gives tall plants while allele "t" imparts dwarfism. Likewise, the dominant allele "P" is responsible for purple flowers while recessive allele "p" gives white flowers.

i) Genotype of Parent 1—Tall plant with white flowers (pure breeding)= TTpp

Genotype of  Parent 2—Dwarf plant with purple flowers (pure breeding)= ttPP

ii) The genotypes of their gametes

Parent 1= Tp

Parent 2= tP

iii) F1 generation = All TtPp (tall and purple flower)

iv) Each of the F1 plant with TtPp genotype will form four types of gametes= TP, Tp, tP and tP

A cross between TtPp x TtPp gives F2 progeny in following ratio=

F2 generation phenotype ratio= 9 tall, purple: 3 tall, white: 3 dwarf, purple : 1 dwarf, white.

Genotype ratio= 1:2:1:2:4:2:1:2:1
