The Lymph and immune system both are systems used to restore health to the body. They fight off unwanted materials and get rid of waste. They both use the Cardiovascular system in order to transport (pump) white blood cells throughout the body.
Answer:
Co-dominance pattern
Explanation:
<em>Co-dominance is a phenomenon in which the two alleles of a gene exert equal effects on each other. That is neither allele of a gene is has the ability to suppress the expression of the other.</em>
On the other hand, the alternate version of a gene represented by alleles are both expressed phenotypically in individuals carrying a co-dominant gene.
<u>Apart from the illustration shown in the question, a good example of co-dominance can be observed in the human ABO blood system in which both allele A and B are expressed in individuals with AB blood group.</u>
Answer: I belive its autosomes
It is faste reproduction, therefor its option D
Answer:
Tongue-rolling is dominant, and both parents were heterozygous
Explanation:
Tongue rolling is a type of variation in human beings. When allelic genes are not identical as in Tt, the condition is referred to as heterozygous. An individual with such a genotypic condition is referred to as a heterozygote.
Both parents had a genotype of Tt and they could roll their tongues because T is dominant over the t gene.
T t
T TT Tt
t Tt tt
TT : Tt : tt
1 : 2 : 1
In a heterozygous parent Tt, the chance of producing T gamete from both parents is each 1/2 each. Similarly the chance of forming t gamete is 1/2. Therefore, the chance of gamete T and t fusing to get genotype Tt is 1/2*1/2=1/4.
The ratios of phenotypes are 3/4 will be able to roll the tongue and 1/4 will not be able to roll the tongue.
The mode of inheritance was monohybrid inheritance since one characteristic like tongue-rolling is controlled by a single pair of hereditary factors contributed by both parents.
