During fertilization, a _sperm_ and _egg_ combine to form a _zygote_.
Sperm and egg (gametes) are both haploid, and the fertilized zygote is diploid.
Answer: Difficulty with communication
Explanation: The cerebral cortex is the thin layer of the brain that covers the outer portion (1.6mm to 5mm) of the cerebrum. It is covered by the meninges and often referred to as gray thing . The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex also covers the cerebellum.
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and <em><u>speech</u></em>, resulting in smooth and balanced muscular activity
Brainly pls Hope this helps :)
Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
