3. Two parent plants are crossed: Plant 1 Plant 2 Phenotype: Solid leaves, smooth skin, normal height x mottled leaves, peach skin, dwarf height Genotype: MM, PP, DD mm, pp, dd a. What is the phenotype and genotype of the F1 generation

Genotype of F1 generation: MmPpDd

Phenotype of F1 generation: Solid leaves, smooth skin, normal height.

Explanation:

This question involves three genes; one coding for leaf shape, skin texture and plant heigh respectively. Based on the illustration used in this question, the alleles for Solid leaves (M), smooth skin (P), normal height (D) are dominant over the alleles for mottled leaves (m), peach skin (p), dwarf height (d).

Hence, in a cross between two parent plants (Plant 1 and Plant 2) whose genotypes are MMPPDD and mmppdd respectively. The following gametes will be produced by each parent plant;

MMPPDD - MPD

mmppdd- mpd

If these gametes are crossed, all the F1 offsprings will have a genotype: MmPpDd, which means they will all phenotypically have: Solid leaves, smooth skin, normal height

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
