Please help with just part one and punnet square

Biology
1 answer:
Inessa05 [86]2 years ago
5 0

The earlobe trait is denoted by E and e alleles, whereas the eye trait is denoted by B and b alleles. The Punnet square allows identifying the expected proportions in the progeny.

<h3>The Punnett square and inheritance </h3>

The Punnett square is a diagram used to represent the gamete combinations in order to estimate genotypes and phenotypes in the progeny.

The earlobe trait is denoted by E and e alleles, thereby there are two types of gametes in heterozygous individuals.

In this case:

           E            e

E        EE          Ee

e       Ee          ee

Moreover, the eye trait is denoted by B and b alleles, thereby there are two types of gametes in heterozygous individuals.

In this case:

           B            b

B        BB          Bb

b       Bb          bb

A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black,
m_a_m_a [10]

Answer:

Alleles for feather colour exhibit incomplete dominance or co-dominance.

50% gray offspring + 50% black offspring

Explanation:

<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>

Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.

Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.

15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.

Bb   x   Bb = 1BB, 2Bb, and 1bb

Crossing the gray rooster (Bb) with a black hen (bb):

Bb   x   bb = Bb, Bb, bb, and bb

          = 2Bb (gray):2bb (black)

50% of the offspring will be gray while the remaining 50% will be black.

What are two characteristics of a scientific information source that may indicate the information is unreliable?
Ksivusya [100]

Scientific information refers to the classification, collection, dissemination, and retrieval of recorded knowledge treated both as a pure and as an applied science. The two features of a scientific information source, which may suggest that the information is not reliable are:  

1. The information is based on data that are not peer-reviewed, that is, the information has not been reviewed by the experts in the field, or is not encouraged by an accord of experts in the field.  

2. The references are not cited, that is, it not clear or not known that from where the information originated.
