Hydrogen bond ! this hold water ( and other molecules with high polarity ) together !
Answer:
c. RrMm x RrMm
Explanation:
A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.
Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).
This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.
The correct answer that would best complete the given statement above would be the term ADAPTIVE RADIATION. African cichlids are a group of closely related fish species. There are at least 500 known species living in three small lakes. Over time, specialized teeth and body colorations have evolved for each species in response to mutations and competition for food and mates. This change over time is an example of ADAPTIVE RADIATION. Adaptive radiation by definition, is <span>the diversification of a group of organisms into forms filling different ecological niches.</span>
In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.
Hope this helps:)
Answer:
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Explanation:
Given
Trait 1 - Recessive allele for green color stem is represented by a
and dominant allele for purple color stem is represented by A
Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"
F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)
The following offspring will be produced
AM AM AM AM
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
