Answer: A- Sill; B- D(i)ke

Explanation:

Sills refers to the concordant igneous bodies that are formed when hot magma intrudes and gets trapped between the relatively older sedimentary rock layers. This are oriented parallel to the ground surface.

D(i)kes refers to the discordant igneous bodies that are formed when the hot intruding magma rises up vertically towards the surface.

Both these structures ranges in thickness from about a few millimeter to a few meters.

Different ratios occur in crosses with single gene pairs or two gene pairs. What types of ratios are likely to occur in crosses
likoan [24]

Answer:

Genotype ratio: 1, 1:1, 1:2:1

Phenotype ratio: 1, 3:1

Explanation:

Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.

For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:

P: AA  x  AA

F1 : all of them are AA

The same is with aa x aa (all of the offspring are with aa genotype)

P: AA  x  Aa

F1: AA Aa AA Aa  (genotype ratio 1:1) (phenotype ratio 3:1)

The same genotype ratio is  in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)

P: Aa x Aa

F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)

P: AA x aa

F1: Aa Aa Aa Aa (1)
