"An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous."
Answer:
The acceleration of object is 2 m.s⁻².
Explanation:
Given data:
Force on object = 80N
Mass of object = 40 kg
Acceleration = ?
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Now we will put the values in formula.
a = 80 N/40 kg
a = 2 m.s⁻² (N = Kgm.s⁻² )
Answer:
1/2 IAIB, 1/2 IBIB (es decir, 50% IAIB y 50% IBIB)
Explanation:
El grupo sanguíneo está determinado por un gen que posee tres diferentes variantes o formas alélicas:
alelo A: IA
alelo B: IB
alelo O: IO
Los alelos IA y IB son codominantes entre sí, es decir, un portador de ambos alelos será de grupo sanguíneo IAIB. Por otra parte, tanto el alelo IA como el alelo IB son dominantes del alelo IO recesivo. En este caso, el cruzamiento entre un individuo heterocigota IAIB con un individuo homocigota IBIB dará como resultado una descendencia 1:1 de heterocigotas IAIB y homocigotas IBIB (es decir, 50% IAIB y 50% IBIB), ya que la madre producirá ambos tipos de gametos en proporciones equivalentes (1/2 IA y 1/2 IB), mientras que el padre sólo producirá gametos IB.
