Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Which part of the brain consists of two large hemispheres, which are divided into smaller areas known as lobes?

vampirchik [111]

Answer:

The answer is the cerebrum.

Explanation:

The brain consists of the following parts; the cerebrum, cerebellum and the brainstem.

The cerebrum is the largest part of the brain located in front. It has two large hemispheres joined by the corpus callosum. The cerebrum has four lobes including frontal, parietal, temporal, and occipital lobes. Functions include: initiation and coordination of movement, memory, touch, hearing etc

The brainstem is composed of the midbrain, the pons, and the medulla. Controls involuntary muscle movements, cardiac function, sneezing etc.

The cerebellum located at the back of the head has two hemispheres. It is controls voluntary muscle movement, posture, balance and equilibrium.

carolus linnaeus created the linnaean system of classification using 2 latin names to designate each organism

Zepler [3.9K]

Answer:

Carolus Linnaeus devised the binomial nomenclature system under which the organisms were named using their Genus name and Species name. The Genus name was written first, forward by the species name. The system of binomial nomenclature allowed for assigning a scientific name to all the organisms so that the conversations between scientists could be made easier. For example, humans have the scientific name, Homo Sapiens, where Homo is the genus name and sapiens is the species name.
