In pole beans, green pods (g) are a dominant trait, while yellow pods (g) are a recessive trait. a bean plant with a gg genotype is crossed with a second plant that has the gg genotype. if this cross produces 500 offspring, approximately how many of the offspring will have green pods? a.0 b.125 c.250 d.500

D (500)

Explanation:

This is a typical monohybrid cross involving one gene coding for pod color in pea plants. The allele for green pods (G) is dominant over the allele for yellow pods (g). This means that allele G will mask the expression of allele g in a combined allelic state.

In a cross between a pea plant that has a GG genotype i.e. homozygous dominant and a pea plant with gg genotype i.e. homozygous recessive, all offsprings will possess a heterozygous genotype (Gg). Since G allele (green) will mask the expression of g allele (yellow), all the offsprings will have phenotypic green pods.

Hence, if the cross produces 500 offsprings, approximately all 500 offsprings will have green pods (Gg)

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
