Olin [163]

Answer:

d a discrete combination of traits, for example Masaai cattle herding.

Explanation:

A cultural complex consists of different cultural traits that together create a 'culture'. Thus, a cultural complex can be defined as a group of cultural traits that are functionally interrelated. A cultural trait can in turn be defined as any acquired knowledge that is learned by social interaction and interpersonal relationships. Moreover, a cultural pattern occurs when cultural traits and cultural complexes associate each other in functional roles.

nexus9112 [7]

Answer:

The probability of getting a dwarf and pink female is 1/2

Explanation:

In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.

A dwarf female from a pure line will have Xd Xd where d represent the  recessive trait and the female is also brownish (pp).

A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).

Y        XDY        XdY                   Y       XPY          XpY

You have an F2 generation derived from two true-breeding parents with different characteristics for the same trait (determined b
castortr0y [4]

Answer:

The percentage for the homozygous dominant trait would be 25%. in the F2 generation.

Explanation:

Suppose true-breeding parents with the different alleles for the same trait are TT (dominant) and tt (recessive) than the cross of these parents will produce gametes T, T and t, t respectively.

These gametes will form offspring ultimately. Produced offspring will be TT (homozygous dominant), Tt (heterozygous dominant), Tt (heterozygous dominant) and tt (homozygous recessive).

Thus, the percentage of dominant homozygous phenotype in F2 would be 25% in respect of the dominant allele which is TT.
