Answer:
The correct answer is cephalocaudal pattern of growth.
Explanation:
Cephalocaudal signifies head to toe, the cephalocaudal pattern of growth is generally witnessed in the initial years of postnatal development, that is, from infancy to toddlerhood. The cephalocaudal development signifies the growth and development starting from the head to the parts below.
In this pattern of growth, the infant possesses the tendency to first acquire their control over the muscles of the neck that makes them hold their head in a steady manner. The cephalocaudal pattern is the tendency of the infant to make use of their upper limbs first like hands before making use of their lower limbs, that is, for crawling or walking.

Answer:
The correct genotype of the two pure lines and the F1 is:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺
The number of additive alleles on each genotype are two and six respectively.
Explanation:
Locus( plural form . loci) are fixed point on a chromosome in which genes are located. These genes are specific genetic material or genotype.
Now;
If we decide to designate the allele of the four loci into either additive (⁺) or non-additive(⁰); we have the following :
Let's the allele of the four loci to be
A⁺/A⁰, B⁺/B⁰, C⁺/C⁰ and D⁺/D⁰
However, from the diagram below; we deduce that the correct genotype for the two pure lines and the F1 is as follows:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺ and the number of additive alleles on each genotype are two and six respectively.
The cross between both F1 traits will yield an heterozygous individual for the offspring. i.e A⁺A⁰B⁺B⁰C⁺C⁰D⁺D⁰ with only four additive allele
