Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
Pleiotrophy effect of a gene where a gene is having many effects.
Answer:
Explanation:
The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others.
The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.
The answer is parasitism.
Answer:
the answer is c.
oceanic acidification is occurring, which results in shelled creatures, clams, lobster, to have weaker shells as a defense. the shells break easily and are too weak to protect the organisms inside, unable to properly calcify their shells leaves them vulnerable to preditors...
